"Ohio Flynn: We've gotta lure that corn colossus away from those backup singers!
 * The Quiet One: Ferb gets two or three lines per episode on average, unless he sings.
 * You can actually make a game out of it by counting how many words he says. On average it's less than ten (Songs notwithstanding)
 * If you make it a drinking game, though, be sure to avoid the episode "The Lizard Whisperer"...
 * Raised by Wolves: Dr. Doofenshmirtz claims he was raised by a family of ocelots after his birth family disowned him.
 * A Rare Sentence: From "The Temple of Juatchadoon":

Isabella: O.M.G, coolest sentence ever! Somebody write that down!

Rhode Island Fletcher: *Does so*"

"Ferb: It usually takes us a montage."
 * Reactive Continuous Scream: In "Comet Kermillian", between Candace and a squirrel. It Makes Sense in Context.
 * Readings Blew Up the Scale: Phineas' cute meter in "The Chronicles of Meap".
 * Real Song Theme Tune: "Today Is Gonna Be a Great Day" by Bowling for Soup, though it was written for the show.
 * Real Women Never Wear Dresses: Averted, especially with Isabella; despite wearing pink and having a fondness for unicorns, she's also beaten Buford at sports, expressed a fondness for gross things and saved her love interest Phineas from trouble about as much as he's saved her. Plus her Fireside Girls' manual includes a lesson on car maintenance.
 * Reasonable Authority Figure: At least within the show's context, Linda is actually an aversion. She's absolutely the only authority figure shown who has any problem with the things Phineas and Ferb do. The episode "What Do It Do?" also shows that when the unusual crops up, her ability to go completely bonkers over it can even rival Candac].
 * Reconstruction: The premise for this show sounds supisciously like all the cartoons you watched back in The Nineties got mashed together in your head, especially the animal superspy and Once an Episode songs part. And damn they do a good job of it!
 * Record Needle Scratch
 * "That Sinking Feeling" has it when the romantic cruise turns out to be for Baljeet; Isabella had been hoping Phineas finally noticed her feelings.
 * Also in "Comet Kermellian" when she says too much about her feelings.
 * "Lights, Candace, Action" has it when we get a toes-to-nose shot of Candace in a beautiful gown that ends with her wearing a monster head.
 * This is actually quite common. A gentle wake-up scene for Candace gets one when she realizes Perry's on her bed, for instance, or the boys spotting Perry with his fedora.
 * Used in "The Wizard of Odd" whenever Phineas and Ferb offered Candace a more fun way to Bustopolis.
 * Recurring Extra: The businessman and his nagging wife.
 * Re Cut: "Phineas and Ferb Christmas Vacation" has an extended edition that restores a cut song.
 * Redheaded Hero: Phineas.
 * Red Herring: Quite literally, in "The Lake Nose Monster". But the Red Herring leads them to Nosey, so it's not a red herring, but it is. Gosh, did they just put that in to confuse people?
 * "Why, yes. Yes they did."
 * Also the pineapple in "Elementary, My Dear Stacy".
 * In "Remains of the Platypus", Doofensmirtz has brainwashed Perry to think he's a butler. Karl laments "Oh, if only you had your hat", and there's an entire sub-plot about Linda finding it..
 * Reed Richards Is Useless: Any creation by the boys, Doofenshmirtz, or anyone else will be undone by the end of episode and not mentioned again, even though some of them have incredible world-changing potential, such as a pair of Stargate-style teleportation rings.
 * Subverted when Phineas mentions "A jellybean-based monetary system for emerging nations...I dunno, I'm just not feeling it!"
 * Well they are kids, and it's implied to be averted outright when the boys get older in time-travel episodes.
 * Reference Overdosed: The show as a whole has a LOT of shout-outs, many of which count as Parental Bonuses.
 * The episodes "Out to Launch" and "The Chronicles of Meap." Try to count all the sci-fi shout-outs (or just the Star Wars ones, if you can't keep up).
 * Refuge in Audacity: This is the reason the boys' mom never believes Candace.
 * Regional Riff: Lots of those, for anytime the cast members are traveling via imagination or literally.
 * Including the Theremin of Outer Space in "My Ride from Outer Space"
 * "It's a Mexican-Jewish Cultural Festival!"
 * Repetitive Name: According to the credits, Carl's full name is Carl Karl, apparently as a way to clear up confusion on the topic (his name being spelled differently before).
 * Reset Button: Played for Laughs, especially with the convoluted and improbable ways P&F's schemes get undone before their mom can see what happens.
 * Retired Badass: The "Doof Dynasty" version of Perry.
 * Rewind, Replay, Repeat: Although they only do one replay; Perry was trying to determine whether Doof's Dull-and-Boring-inator had fired before being destroyed. It had.
 * Ridiculously Cute Critter: Meap is made of this.
 * Baby Perry.
 * Also, Mitch, when he
 * Lets put is simple and make that every darn member of his and Meap's kind.
 * Ridiculously-Fast Construction: One episode lampshades this by having Phineas begin building a submarine at the same time Isabella begins making a cheese sandwich. When Isabella returns with the sandwich, Phineas is just finishing up the submarine.
 * Lampshaded again the second time they build a submarine (to search for Buford's missing fish), complete with fourth wall breakage

""I don't have to pt up with this, I'm part of the greatest generation!""
 * Also lampshaded in Candace Disconnected, in which Phineas tells Candace that it took 40 years to come up with cellular phone technology, so they can build her one in 38 minutes. And they build two. With teleporter functionality.
 * Not to mention in "Just Passing Through" when Baljeet complains that "you can build a rollercoaster in a day, but it takes you twenty minutes to fix a flat tire?!" (Paraphrased.)
 * Right Behind Me: One of the many reasons Doofenshmirtz has been beaten up by big characters.
 * In "The Monster of Phineas-n-Ferbstein" Constance uses this, word-for-word.
 * Candace once manages to do a Right In Front Of Me. To clarify, she's insulting the animals that are in front of her, not realizing that a animal translator is right behind her.
 * Roger Rabbit Effect: The Spin-Off Take Two With Phineas and Ferb. See Spin-Off below.
 * Rosencrantz and Guildenstern Are Dead: The episode "Isabella and the Temple of Sap" chronicles the lengths that the titular character and her Fireside Girls troop are prepared to go through to get an object used by the boys in the previous episode.
 * Rousing Speech: In "Lizard Whisperer", and it's his Crowning Moment of Awesome!
 * Phineas gets one in "Meatloaf Surprise" as well.
 * Rousseau Was Right: The Big Bad is not evil.
 * Averted in the movie; Doof2 had a far less traumatizing Backstory, but is Eviler Than Thou.
 * Rule of Funny: Loaded with it.
 * Rummage Fail: Doofenshmirtz's remotes in "Lawn Gnome Beach Party Of Terror".
 * Running Gag: The show masters this to perfection.
 * Particularly the catchphrases. Just look at the entry! Almost all of these things are said once every ten-minute episode!
 * Ruritania: Druelselstein.
 * Rushmore Refacement: "Candace Loses Her Head".
 * Sadistic Choice: In "The Beak", Phineas and Ferb have to pick between Isabella falling to her death or letting a billboard fall on people. Third option? There are two components of The Beak. Phineas (in control of the upper body) somehow gets out to save Isabella and Ferb (in control of the lower body) takes care of the falling billboard.
 * Sadist Show: Explicitly averted by the creators as mentioned in this article.
 * Sanity Ball: Whenever Candace is in full busting mode, expect her to drop this.
 * And during a few of Doof's more absurd schemes, most notably the one in "Perry Lays an Egg".
 * Sanity Slippage: Candace is having a sort of series-wide version, due to her busting attempts and hallucinations becoming more and more Flanderized as the the show goes on.
 * Saving Christmas: Subverted,
 * Saw It in a Movie Once: Doofenshmirtz uses a villain deathtrap on Perry, saying he "saw it in a movie once."
 * He then goes on to add that he "didn't see the end, but it seemed pretty foolproof."
 * To be fair, it was the laser scene from Goldfinger, which Bond didn't actually escape (the villain turned it off after deciding to use him in a ploy rather than kill him).
 * Also, in "That Sinking Feeling", Phineas claims they've seen a movie about a cruise ship sinking, and it seemed to have worked wonders for the romantic aspect of the film, which is where they got the idea for Baljeet's date with Mishti.
 * Scenery Censor:
 * Doofenshmirtz, while explaining his plan to flood the coast and make his house beachfront property, rips off his outfit to reveal... The edges of a speedo peeking out from above the wooden railing in front of him.
 * Happened to Ferb once too. Good thing he had that giant spool...
 * More than once, actually—it happened again in Swiss Family Phineas.
 * Science Fair: The subject of two episodes, appropriately named "Unfair Science Fair" and "Unfair Science Fair Redux".
 * Schizo-Tech: While arguably invoked all the time, the episode "Doof Dynasty" shines a bright spotlight on it. Taking place in 1542 in China, they often talk about Phineas and Ferb using "tech slightly more advanced than we have today."
 * Scooby-Dooby Doors:
 * In "One Good Scare Ought to Do It!"
 * And again in "Phineas and Ferb's Hawaiian Vacation".
 * A variation appears in the song "Livin' in a Funhouse".
 * Scout Out: The Fireside Girls.
 * Screwed by the Network: Despite the exact opposite. Phineas and Ferb are subject to frequent marathons and specials across both of Disney's major channels, and they play a big part in a lot of the channel bumpers and advertising, but during the middle of Season 2 new episodes were subject to some severe Schedule Slip, to the point where they would air in other countries months before the US premieres, which are about a month apart from each other themselves. The premieres have since been getting more regular since the start of Season 3.
 * Screw Politeness, I'm a Senior!: From "Lotsa Latkes"

"Candace: I'm sorry we had to clean up everything we destroyed... and had to rebuild it. I'm especially sorry I made us miss our spa appointment. But most of all, I'm sorry for being a bad friend. I was just trying to impress Jeremy and I lost sight-- Stacy: Okay, you can stop that right now. You're starting to sound like one of those TV shows we like to make fun of."
 * Screw This, I'm Outta Here: Buford, when "Candace" says something weirdly out of character in "Make Play".
 * Also done by Perry when he discovers Doofenshmirtz's plan in "Perry Lays an Egg".
 * The Scream: Ashley Tisdale, AKA Candace, is very good at screaming.
 * Secret-Chaser: Candace.
 * Secret Ingredient: In "Meatloaf Surprise", the secret ingredient in the Doofenshmirtz family meatloaf recipe is hate. "Usually it's love, but Great-Grandma Gretel had some issues."
 * See-Thru Specs: "No More Bunny Business", where Phineas and Ferb created X-Ray Glasses.
 * Selective Gravity: In this case, gravity applies to most things, but not to Perry's fedora hat, to give an example.
 * Self-Deprecation: In Spa Day:

"Phineas: Hey, where's Vanessa? Ferb: She went off with someone else.
 * Done to cartoon makers in "Out of Toon".
 * Self-Parody: In "The Wizard of Odd", the credits contain the song "Rusted", a parody of the earlier Phineas and Ferb song "Busted".
 * Also "Perry the Teenage Girl" (parodying Perry's regular theme) and "Couldn't Kick My Way Into Her Heart" (parodying "Snuck Your Way Into My Heart").
 * Sensitive Guy and Manly Man: Baljeet and Buford, respectively.
 * Series Goal: For Candace: Bust the boys. For Doof: Take over the ENTIRE TRI-STATE AREA!!!!!!!!!!
 * Phineas and Ferb, by contrast, accomplish their goal every day.
 * Serious Business: In the Clip Show episode, Perry gets called into the OWCA headquarters so that they can tell him that his performance has been suffering. It turns out that they mean that his entrances have been getting boring, not that his mission performances have been poor. The look on Perrys face indicates that he is very upset by this.
 * Sesquipedalian Loquaciousness: Fireside Girl Gretchen has moments of this, as does Baljeet. Gretchen even used the word 'sesquipedalian'.
 * Good luck understanding/knowing half of the words Buford and Candace say in "Let's Take a Quiz".
 * Set Right What Once Went Wrong: Future Candace in "Phineas and Ferb's Quantum Boogaloo".
 * Sex Bot: Baljeet's backup singers in the song "Takin' on the Big Brain" in "Cranius Maximus".
 * Shaggy Dog Story: Candace earning all 50 patches of the Fireside Girls to get tickets to the Paisley Sideburn Brothers concert, only to learn that Isabella could bring guests with her.
 * A lot of episodes end like this for Candace.
 * Shallow Love Interest: Some fans feel this way about Jeremy when he was first introduced. Later episodes like "Nerdy Dancing" and "The Lizard Whisperer" seem to be trying to develop him a bit more.
 * Shaped Like Itself: The song "Little Brothers". Also, "Space Adventure! It's an adventure in space!"
 * "That's a very nice imitation of yourself, Candace."
 * Shapeshifter Showdown: Doofenshmirtz and Perry have one in "Phineas and Ferb: Hawaiian Vacation!", though this is a rare example where neither of them have any control of what creatures they turn into, so they just have to make the most of it.
 * Shiny Midnight Black: Isabella.
 * Shipper on Deck: Candace/Jeremy also gets support from basically everybody but Suzy.
 * Judging from this bit, Phineas seems to be a Ferb/Vanessa shipper.

Phineas: That's too bad. I thought the two of you, you know, a boy, a girl, alone, in the City of Love -- I thought romance was a forgone conclusion!"

"Sometimes photons behave like a wave, But they're particles when you reflect 'em."
 * Doofenshmirtz seems to be a Johnny/Vanessa shipper, despite what one would expect. In an in-character DVD Commentary for "The Chronicles of Meap", however, he objects to Ferb hitting on Vanessa.
 * Ship Tease: Phineas and Isabella, constantly.
 * It's almost confirmed in "Phineas and Ferb's Quantum Boogaloo", when Amanda refers to Isabella as her aunt. A twist is added when Candace points out that Isabella will still be an aunt if she marries Ferb. Then Ferb starts flirting with her.
 * This is it, Isabella (and Phinbella shippers)! She's finally going to spend some time alone with Phineas at the end of "Canderemy"!!
 * Don't forget midway through "Candace Disconnected", Phineas teleports directly in front of Isabella, so close that his nose is literally touching hers. She acts her normal flirtious way, but Phineas doesn't get it when he teleports away, as usual. Still, it's the closest those two have EVER gotten to a kiss.
 * The creators seem to like teasing lots of different pairings, actually—aside from the Official Couples they've also dropped hints that Baljeet may have a crush on Isabella, Vanessa flirts with Jeremy at one point before quickly losing interest, and Albert's interaction with Candace...
 * And for some reason, Perry and Doofenshmirtz despite the species difference.
 * Show, Don't Tell: Defied in one episode to parody the Silent Bob trope.
 * Shown Their Work: Though they do sometimes forget to do this, there are plenty of examples. Take, for example, the Tsiolkovsky rocket equation gag from "Out to Launch". With the obvious exception of the bomb/smiley face punchline, that is what the Tsiolkovsky rocket equation looks like.
 * Take this line from the song "X-Ray Eyes".

"Doofenshmirtz: You're not going to tell me? Is this because you don't speak, or are you just being a jerk?"
 * The Lion-Tiger-Bear Guy from "The Wizard of Odd". No, it's not just a pun on the famous quote, there is an animal in the original Wizard of Oz book that is a hybrid of all those animals.
 * Shout-Out: Has its own page.
 * Shrug of God: The creators, when asked Phineas and Ferb's age; though the original pitch called them nine, this was retracted so that now they're merely "less than fifteen".
 * In "Quantum Boogaloo", however, they had to pick an age, so ten was given, as twenty years in the future Future Linda says that the boys are thirty years old. However, she may have been rounding; Word of God was that fans shouldn't necessarily take her literally.
 * Sibling Rivalry: A one-sided case with Doofenshmirtz and his brother.
 * Also a less extreme, but also one-sided example would be Candace against her brothers, though when the boys aren't inventing, the three get along just fine.
 * Sibling Team: The titular brothers, especially when the rest of the gang isn't around.
 * Sibling Triangle: Quantum Boogaloo" reveals that Isabella is going to marry one of the Flynn-Fletcher brothers. It will probably be Phineas, but Ferb seems to hint that he's keeping his options open.
 * Sibling Yin-Yang: In many ways, Phineas and Ferb, though they see this a more of an advantage than a drawback. (Well, technically, they're stepbrothers, but they never refer to themselves as such).
 * Also, both the boys and Candace.
 * Sick Episode: Phineas, Ferb, Isabella and Bajeet are all in bed with colds in "Brain Drain".
 * Buford is just lazy though.
 * Candace had one in "Put that Putter Away", forcing her to hire Stacy to do the brother-busting for her.
 * Sigil Spam: One of the main symbols of the show is the triangle, since Phineas' head is shaped as such. Thus, it's put everywhere when a mono-color background is used (most of the time for a song).
 * Silent Bob: Ferb.
 * Silent Partner: Ferb, mostly.
 * Silent Snarker: Perry is a master at this.

""Or we could just hit it with a rock.""
 * Ferb could count since he rarely talks, and spends more time rolling his eyes at the weirdness of his peers. He does some Deadpan Snarking too, though.
 * Simpleminded Wisdom: In "The Temple of Juatchadoon". Twice.

""A-G-L-E-T, don't forget it!""
 * Simpleton Voice: Doofenshmirtz has a bizarre voice that not only tells you in a second that he is a total idiot, but also that he is evil and certifiably insane.
 * Single-Target Sexuality: Isabella never had a crush on anyone but Phineas.
 * Except the Beak. Who turned out to be Phineas (and Ferb).
 * This trope mostly applies to Candace regarding Jeremy. She had a crush on a British guy named Charles during their visit to England in "A Hard Day's Knight", an episode set before they became an Official Couple.
 * Although, he looked exactly like Jeremy... Only British. And richer.
 * We can hardly blame her for considering other boys, since she'd been trying to make Jeremy her boyfriend since 5th grade, and hadn't succeeded yet as of the end of 9th grade.
 * Sitcom Arch Nemesis: Doof and Rodney really have this thing going between them.
 * Sinister Schnoz: Doofenshmirtz has a long nose. Sinister, though...
 * Skirts and Ladders:
 * One of Candace's inventions (long story) is picked up by Doofenshmirtz's hook, she's forced to dangle from the edges while Stacy hangs onto her legs. She glances up her skirt but quickly looks down after that.
 * Doofenshmirtz is very close in getting an upskirt view of Candace in The Movie while the main characters dangle in chains above a lava pit, but for most of the time, he was looking down.
 * Skyward Scream: During Candace's Big No from "Gaming the System".
 * Parodied in the song "Way of the Platypus"
 * Slapstick Knows No Gender: Candace gets put through the wringer practically Once an Episode, but like Wile E. Coyote it's only her "busting" obsession that puts her there. The Fireside Girls do a fair amount of physical gags, too.
 * Sliding Scale of Idealism Versus Cynicism: Extremely idealistic, as long as creativity isn't crushed.
 * Snap Back: Doofenshmirtz seems to get into very compromising situations (some of which seem out-and-out irreversible) and be okay again by the next episode.
 * Every object in the Universe is expanded to 9 times its size by Phineas and Ferb's growth elixir in "Attack of the Fifty Foot Sister", but is somehow reversed later offscreen.
 * Or not... Once every object in the universe was hit, relative sizes all matched again. If it never got corrected, who would know?
 * . (Granted, it's implied that Phineas and Ferb try to fix that one, but that still doesn't explain .)
 * In "It's About Time", Monogram appears to have been hit by Doof's -inator of the day offscreen, turning him into a immobile statue. This isn't shown to be fixed by the end of the episode.
 * Invoked in "Agent Doof", where, causing Candace to hope that everything is back to normal by the next episode.
 * Snipe Hunt: In "Undercover Carl", Major Monogram sends Perry on a literal wild goose chase because Phineas and Ferb were allegedly involved in Doofenshmirtz's daily scheme, and he feels that Perry is too close to the case.
 * Snowclone Title: Quite a lot. Heck, there was even one in the Japanese version.
 * Sorry I Left the BGM On: Stacy's Song "Little Brothers".
 * Doofenshmirtz sets up a trap with a piano hanging over the door. As the trap is revealed dramatic music plays ... from a man sitting at the piano.
 * Again in "She's The Mayor".
 * Solo Duet: Two counts; the first in 'Mom's Birthday' with a recorded version of Candace and Candace singing live. The second is from 'Split Personality' where the two Candaces sing a duet about how happy they are to be separate.
 * Soundtrack Dissonance: "It's a Perfect Day" playing while Candace is being chased by a mob of angry animals.
 * To a lesser extent, the spa day was accompanied by a rap song.
 * Spaghetti Kiss: Almost done in "Summer Belongs to You"....with Buford and Baljeet.
 * Species Surname: All of the O.W.C.A. Agents, except Pinky the Chihuahua.
 * Stating the Simple Solution: This is Doofenshrmirtz' thing. Subverted in that it is Doof himself who states the simple solution, only to dismiss it himself because that alternative, truly simpler solution would be "too complicated".
 * Speech-Impaired Animal: Perry.
 * The Speechless: Again, Perry. He is an animal, after all.
 * Spelling Song: From "Tip of the Day"

"Phineas: Remind me again why did we put spikes on Buford's chariot?"
 * Spiked Wheels: During "Greece Lightning", Buford has them.

"Candace: Who puts a picture-frame on a window?"
 * Spin-Off: A mix of animation and live-action called Take Two With Phineas and Ferb, in which the characters interview Real Life celebrities. To date, they've covered Jack Black, Andy Hawk, Tony Hawk, Taylor Swift, Regis Philbin, Neil Patrick Harris, Randy Jackson, Emma Roberts, Cedric The Entertainer, David Beckham and Howie Mandell. Miss Piggy and Ty Pennington will appear in future episodes.
 * Split-Screen Phone Call
 * Spoiler Title: "Candace Gets Busted".
 * Squeaky Eyes: Happens occasionally, usually during a Beat. Ferb usually has the squeakiest of all of them.
 * Squirrels in My Pants!: Trope Name-inator.
 * Stalker with a Crush: Candace arguably fits this role, particularly in the early episodes where she does things like photograph Jeremy hundreds of times and watch him through binoculars instead of just walking up and talking to him, not to mention her elaborate lists and scrapbook projects (which are apparently a secret from everyone besides Stacy). It seems it's not in the nature of this family to do things by halves.
 * Not a typical example of this trope in that Jeremy and Candace develop a healthy relationship based on mutual affection. But the affection on the one side continues to be highly obsessive.
 * Stand in Portrait: Candace in the opening theme. Used again in the episode "Fireside Girls Jamboree".

"Doofenshmirtz: And who would have guess it, it all goes back to normal. Explosion....now."
 * Star Trek Movie Curse: Referenced in "Nerds of a Feather" with the Space Adventure movies.
 * Status Quo Is God: Whenever Candace realizes that her brothers aren't actually nuisances, she warms up to them. But by the next episode she's back to her normal frantic self.
 * Of course, one of the biggest jokes of the series is that no matter what happens, it will all go back to normal. Somehow.

""If you worry 'bout the sound you can always scream into a pillow"."
 * In one episode, the characters actually make the entire freakin' universe grow several times larger in order to return things to normal. That just goes to show how extreme this show goes in order to follow this trope.
 * Stealth Pun: Love Händel is named in the style of '80s rock bands, and the pun becomes hilarious when one realizes that people who listened such bands in their heyday are now middle-aged.
 * In "Lights, Candace, Action!" Candace's personal trainers are a pair of fleas.
 * Roger and Heinz Doofenshmirtz's caddies in "She's the Mayor" are Katy and Perry, respectively.
 * Phineas solved one of the puzzles in 'Escape from Phineas Tower' by undoing a lock with a bone. That is to say, a skeleton key.
 * Stepford Smiler: In musical format, no less. It's really not obvious until the last line:

"Doofenshmirtz: Perry the Platypus! *hides raygun* There's no one else here!"
 * Sting: Used a lot for comedic effect.
 * Stock Audio Clip: Candace: several different screams, "Meep...". Perry: chattering. Isabella: "Whatcha doin'?". Bob Weber: "OK!"
 * Stock Footage: Being a remake of the very first episode IN SONG, "Rollercoaster: The Musical" reuses a lot of footage from that episode (though most of the reused lines were rerecorded and some of the jokes were changed).
 * Stock Ness Monster: The Lake Nose Monster.
 * Stylistic Self Parody: Carl explains he has no sense of smell since he was born without nostrils, alluding to the way his nose is drawn.
 * In the Clip Show episode, Doof tries to use his hand to signal the number 'four' but realizing he wasn't drawn with quite enough fingers, he also stuck out his thumb.
 * Several episodes poke fun at Candace's outlandishly elongated neck.
 * In "Hide and Seek", Doofenshmirtz sees Phineas and Ferb with their friends on camera and mistakes them for a "kiddie TV show".
 * Monogram points out that he can see the smell of Carl's sandwich in "Misperceived Monotreme".
 * Monogram and Doofenshmirtz comment on Phineas having a triangle head and Ferb having green hair in their commentary for "The Chronicles of Meap".
 * In the halloween episode, Carl notes that his Monogram Desguise isn't complete because he couldn't put both eyes in the same side of the nose.
 * Stylistic Suck: Doof'n'Puss - a show Doof pitched to Seth... I mean Jeff McGarland. With such insane premise and ridiculous plot...
 * The Stoic: Ferb doesn't have a whole lot of expression—notably, his face remains completely blank as Phineas employs Puppy Dog Eyes to persuade Candace to keep Nosey's secret in "The Lake Nose Monster".
 * Perry as well, though it's more of a "cool, steely" example than an "entirely emotionless" one.
 * The Stool Pigeon: Candace.
 * Strange Minds Think Alike: Occurs often enough, often with an episode's Running Gag.
 * Strange Syntax Speaker: In the episode "Make Play", Princess Baldegrunde talks like a German accented Yoda who just suffered a head injury.
 * While this initially seems like a result of her not being fluent in English, Ferb reveals that this is the proper syntax for royalty to speak in her country. Then they just shrug it off and continue to assume she's Candace.
 * Strictly Formula: And loving it.
 * And the creators know just when to break formula, if just for an episode.
 * Many, many episodes lampshade this, especially with Perry and Dr. Doofenshmirtz.
 * Stuff Blowing Up: Random objects explode during the fight scene against the Ninja Vampires in "Doof 'n' Puss".
 * Stuffy Brit: Ferb kinda counts. He has plenty of warmth, he just shows it as often as any emotion, which is very rarely.
 * His dad, on the other hand, severely averts this.
 * Styrofoam Rocks: Played with. When they are constructing their life-sized replica of Niagara Falls, Ferb (on the ground) picks up a boulder and throws it all the way to the top of the structure. Phineas says that even though he knew that that was paper-mâché, the throw was still very impressive.
 * They show up again in "The Great Indoors", when Jeremy tries to explain to Candace that they're just paper-mâché.
 * Stupid Statement Dance Mix: In universe example, "There is No Candy in Me".
 * Suck E. Cheese's: "Gunther Goatcheese's! The goatcheesiest place in all of Druselstein!"
 * Sudden Anatomy: Perry only has teeth when they're needed for an expression.
 * He also only has fingers when he's in his agent mode. Otherwise, his hands are merely little pads.
 * Sudden Downer Ending: Specifically for Doofenshmirtz in "Chez Platypus". During the entire episode, he goes on a date with an equally evil girl, falls in love, sings the most adorable Villain Song in history with her, and then says that he has "Never been so happy in his entire life".
 * Summon Backup Dancers: Often. In "Rubber Bands and Rubber Balls" the factory has a breakroom specifically for them.
 * Doof also has back-up dancers during his musical numbers. We see him paying them afterwards.
 * Super OCD: Phineas' obsession with inventing things in "Bully Bromance Breakup" is either this, or a G-Rated Drug.
 * Suspiciously Specific Denial: In "It's About Time":

""Today on "The Morty Williams Show," "My Kid Is Bad, and I Want to Blame Others!"""
 * Sympathetic Inspector Antagonist: This is how Candace considers herself.
 * Synchronous Episodes: "Unfair Science Fair" and "Unfair Science Fair Redux", both shown in the same half hour.
 * Again with "Bubble Boys" and "Isabella and the Temple of Sap".
 * Take Over The Tri-State Area: Doofenshmirtz's goal. Most of the time.
 * Take That: Squarely aimed at Standards and Practices in "Raging Bully".
 * "Look! A sponge and a starfish! There's gotta be something we can do with these... oh, no, that's ridiculous!"
 * There was a jab at Moral Guardians in "Quantam Boogaloo". And what a Take That it was!
 * There was also one directed quite squarely at parents who blame the media for their kids acting bad instead of their bad parenting in "Phineas and Ferb Get Busted".

"Phineas: We might even arrive in Danville ahead of time! Y'know, barring any unforeseen mishaps. *cue boat falling apart*"
 * Take That, Audience!: In the song "Hey Ferb", Phineas brings up how glad he is not to have spent his summer vacation sitting and watching TV, while "Summer Belongs to You" encourages the audience to "not waste a minute sitting on that chair". Both of these activities are likely to be what the viewer is doing... in order to watch the show.
 * The Beak Song states that you're pretty weak compared to the Beak
 * Talking Animal: Candace when she switched bodies with Perry (the Platypus).
 * Talking the Monster to Death: In "The Beak", Phineas and Ferb try this with Khaka Peü Peü (*snicker*) when they realize he was only on a rampage because he had never had a "greatest day ever" himself. However, the attempt fails when it turns out KPP has an opposing concept of a great day than the boys do, and he's instead defeated when a chair is thrown at him from offscreen a few moments later.
 * Talking with Signs: Meap
 * The Tape Knew You Would Say That: A variation - in "Meapless in Seattle" Linda was listening to french language learning tape, that described what happen right behind her.
 * Team Rocket Wins:
 * The Team Wannabe: Irving, originally. He's now a sorta an unofficial Sixth Ranger.
 * Tears of Remorse: In the appropriately titled episode "Phineas and Ferb Get Busted", Candace starts crying when her brothers get their personalities and imaginations cleared because of her actions, as she tells them that she's always been proud to be their big sister and begs them to come back.
 * Teleporter Accident: Played straight (complete with Lampshade Hanging and Shout-Out to The Fly) and then subverted via additional phlebotinum.
 * Tempting Fate: Phineas is the king of this in "Summer Belongs to You!" where even as bad things keep happening, he won't stop talking.

"Phineas: Looks like a real summer storm! Well, our plan to stand alone in a field with a metal rod is out."
 * Also:

"Doofenshmirtz: Yeah, I wasn't very clever with names back then so it was just 'Inator'."
 * "You can't stop me, Perry the Platypus! You couldn't stop me with a billion Perry the Platypuses!" Cue Doof falling through a skylight, straight into the assembly line making hundreds of Perry the Platypus toys.
 * "This building is so well-constructed, there is no force on Earth that can move it before your mom gets home!" And then
 * Ten-Minute Retirement: Phineas, of all characters, gets one in "Summer Belongs To You!"
 * Tertiary Sexual Characteristics: The revere-engineered -inator in "What Do It Do?" has long eyelashes.
 * The female Aqua Primates are pink/red and have long eyelashes.
 * And Perry suddenly has long eyelashes when he switches bodies with Candace.
 * That Poor Cat: A bird flying into the latest tall project or getting hit with something a giving a pathetic squawk is an occasional running gag.
 * That Russian Squat Dance: Done by Doofenschmirtz's guards in "The Wizard of Odd".
 * That Thing Is Not My Son: Subverted, as most of the tropes are. When Doofenshmirtz thinks he's insulted Vanessa by saying he'd rather have a son than a daughter, Norm tries to be a surrogate son. Doofenshmirtz repeated refuses to acknowledge him as such, though.
 * Theme Music Power-Up: Whenever Perry does something awesome (i.e.: every other scene he's in), his theme song plays.
 * There Was a Door: Very frequently Lampshaded, up to the point where, Doofenshmirtz actually convinces Perry to pay for the broken door.
 * He gives Perry keys, too, and they are repeatedly mentioned. Doofenshmirtz never fails to praise him for using them. There is still generally a trap, though.
 * Isabella and the troop could have just as easily "driven" their van through the archway at the park, but NOOOO, they just had to go through the wall, didn't they?
 * They Fight Crime: A fugitive semi-aquatic special forces amateur stage magician framed for a crime he didn't commit- the 1865 assassination of Abraham Lincoln - joins forces with a rogue trillionaire inventor extreme fighting champion from the future. Together with the aid of R.I.C.K., their super crime-fighting high-tech talking rickshaw, they'll bring hope, justice, and varying degrees of aquaticness to a tri-state area in peril. Together, they are...Doof 'n' Puss.
 * Thinginator: If you watch a marathon of this show, and take a shot for every time you hear the suffix "-inator", you will be fall-down drunk in no time.
 * Doof occasionally uses a pair of "-inator" suffixes, with a hesitation before the second one.
 * Lampshaded in "Unfair Science Fair" when Doofenshmirtz flashes back to his first science fair and talks about his very first invention, called simply 'INATOR'.

"Doofenshmirtz: (on a Mexican Soap Opera) It has three simultaneous story lines that interconnect. Genius!"
 * -inator seems to have been retooled into referring to pretty much any device intended for evil in later episodes. In "Finding Mary McGuffin", Doof refers to his recent purchase as simply an -inator, since he didn't know what it did and couldn't give it a proper name, and in an evil scientist contest, the devices they build are all referred to as -inators.
 * And then retooled again, with every Mad Scientist apparently using their own unique naming convention for their devices. So far, Doofenshmirtz sticks with "-inators", Rodney uses "-izers", and Dr. Diminutive uses "-erators".
 * Third Line, Some Waiting: Occasionally there's a Candace subplot.
 * Lampshaded (like everything else in this series):

"Candace: Get away from him, Mitch!"
 * This Is for Emphasis, Bitch: G-Rated subversion in "The Chronicles of Meap":

"Phineas: Can I have everyone's attention? Please don't panic. We're experiencing technical difficulties. Calmly head towards the exit in a calm, orderly-- A large chunk of structure falls right behind him. Phineas glances at the fallen rock.
 * This Is No Time for Knitting: In the DVD character commentary of "The Chronicles of Meap", Doofenshmirtz is shocked that Candace would play baseball in a life-or-death situation, while Monogram (quite rightly) realizes that she's saving the day.
 * This Is No Time to Panic: From "Comet Kermillian", we get this gem:

Phineas: Okay, now you can panic."

"Phineas: Yeah, we're inside Candace's stomach. Ferb: That's creepy on so many levels."
 * This Is Wrong on So Many Levels: From "Journey to the Center of Candace", when the boys find out they're inside Candace's body:

"Phineas: Candace is on her date with Jeremy. That means we're on a date with Jeremy. Ferb: Again, creepy on so many levels."
 * And later...

"Audience Member: This stinks so bad I wanna break somethin'! (He grinds his teeth together and they shatter with the sound of glass breaking.) Audience Member: ... Yeah, that really wasn't worth it."
 * This Loser Is You: Irving the fanboy in "Hide and Seek" is this personified.
 * Actually, he's meant to be merely an affectionate parody of the fans of the show, he just came off as this way to certain people.
 * "The Beak's" theme song seems mostly to consist of deriding the listener for not being as awesome as The Beak.
 * Those Two Guys: Buford and Baljeet, combined with Friendly Enemies.
 * Training Montage: "Your opponent is as big as an ape, so if you wanna avoid being mangled..."
 * "In other circumstances you might fail, 'cause I know you don't have a beaver tail..."
 * Throw the Dog a Bone: Candace does occasionally benefit from the boys' ideas and gets with Jeremy.
 * Don't ever play Skiddley Whiffers with Candice, because she'll beat you.
 * Heck, Jeremy may possibly be the physical manifestation of this trope to Candace on the show. Despite all the horrible things that happen to Candace and her futile efforts to bust her brothers, Jeremy's mere presence (along with a kind word or a helpful gesture) would always lift her spirits up somehow.
 * In "That Sinking Feeling",.
 * Every now and then, good things happen to Doofenshmirtz. Although most of those tend to be yanked away, one of the ones the weren't (and usually one of the most satisfying parts of the series) are the times when Vanessa actually acknowledges that Heinz is actually a pretty decent dad, all things considered.
 * A good example is "We're Getting the Band Back Together". While Doof was defeated by Perry, the launch of the giant firecracker burned all the birthday decorations for Vanessa's party, giving the area a gloomy atmosphere that she actually enjoyed. The firecracker also launched him straight to the Love Handel (his favorite band) reunion concert, which he hadn't even been aware was happening and would have missed otherwise.
 * In "Finding Mary McGuffin", Doofenshmirtz manages to get out of being beaten by Perry since the -inator he purchased didn't actually do anything evil, and he even seems to get a chance to bond with Vanessa at the end.
 * Sadly averted in 'Chez Platypus' when Doofenshmirtz finds his perfect second half with all and a crowning music of awesome,
 * Toilet Humor: Not nearly as much as you'd expect from a kid's cartoon, but yes, Doofenshmirtz, Buford, and Baljeet being the main dealers of it.
 * The Tri-State Area Is The Center Of The Universe: One of Doofenshmirtz's flashbacks in Season 2 actually explains why he concentrates on just the Tri-State Area. Why everyone else does is probably Rule of Funny.
 * Tongue on the Flagpole: Happens to Doofenshmirtz in "Out to Launch".
 * Too Dumb to Live: Dr. Doofenshmirtz's utter lack of common sense has, on more than one occasion, put himself into a situation where he would have been seriously injured or killed if he didn't posses Joker Immunity.
 * Took a Level In Kindness: Buford.
 * Too Soon: In "Let's Bounce," as his Lincoln robot betrays Doof, Doof cries out, "He's gonna John Wilkes my Booth!" Then he looks at Perry and say, "what, too soon?"
 * The Tooth Hurts: In "Bubble Boys", during Dr. Doofenshmirtz's attempt at country-western singing:

"Candace: (snap) Okay! Webber: I don't get it."
 * Toothy Platypus: Perry
 * "The Tri-Stone Area" has toothy vultures.
 * Torches and Pitchforks: The Angry Mob in "The Monster of Phineas-n-Ferbenstein".
 * Trademark Favorite Food: Ferb loves himself a good submarine sandwhich.
 * Several other(often one-shot) characters as well. The defrosted Neanderthal Kronk and the platypus from "Misperceived Monotreme" are both crazy for sandwiches, Candace and Pinky narrow it down a bit to grilled cheese sandwiches, Steve the Chameleon loves mushrooms, and Dennis(or Mr. Cutie Patootie) was undone by his obsession with carrots.
 * Trailers Always Spoil: The promo for "Candace Gets Busted" basically said it all - it ended up as a small get together, but then escalated into an insane party, and shows Linda grounding Candace. Then it gives a clip of the song "Intimate Get Together" from said episode.
 * Translator Microbes: The Universal Moustache Translator in "The Chronicles of Meap".
 * Tree Buchet: in "Rollercoaster". There's also an Eiffel Tower-buchet, and a Statue of Liberty-buchet.
 * Treehouse of Fun: The boys once rebuilt their and Candace's treehouses, with an additional feature to transform into battling robots.
 * Troperiffic: Considering the creators...
 * "Oh, this is like one of those sitcoms where somebody says something that's misconstrued and the snoopy next door neighbor gets the wrong package delivered after his in-laws come to visit and somebody has two dates on the same night and they have to paint a white line down the middle of the room. But this isn't a sitcom, Perry the Platypus. This is real life." [Cue both Perry and Doof looking straight at the audience.]
 * Any time this happens, there's a 99% guarantee it will be lampshaded.
 * Tropey Come Home: "Come Home Perry".
 * Tuckerization: In "Dude We're Getting the Band Back Together", the band members are named after series creators Dan Povenmire, Jeff "Swampy" Marsh, and Bobby Gaylor.
 * Which could also double as Meaningful Name. The Ambiguously Gay Camp Gay Bobbi Fabulous anyone?
 * Ferb is named after a friend of the creators, who is also quite talented in building things, but is, "anything but silent".
 * Isabella is named after Dan Povenmire's daughter, with the one-time character Melissa being named after his other daughter.
 * Tuxedo and Martini: Agent Double 0-0, minus the martini. Agent P has also been seen in a tuxedo a few times.
 * The Television Talks Back: Happened with Candace in "Flop Starz"
 * Also apparently happened between Lawerence and Major Monogram in "Comet Kermillion", though it's a rare justified example.
 * Twitchy Eye: Has happened to Candace on more than one occasion.
 * Also happened to Linda in "Split Personality" when Candace's romantic half won't stop talking about Jeremy.
 * Two Candace Rule: Several episodes (and the movie) have two Candaces onscreen at the same time for extended periods. Any scene with three or more Candaces lasts only seconds.
 * Two Lines, No Waiting: Most of the episodes have the Phineas and Ferb/Candace plotline and the Perry/Doof subplot.
 * Twofer Token Minority: Isabella, whose last name is Garcia-Shapiro. implying that she's Hispanic and Jewish. Her mother confirms the Hispanic half (she also says "oy"), and the Jewish half is also confirmed with the Mexican-Jewish Cultural Festival.
 * Further confirmed in the Christmas special, when she notes her family celebrates Hannukah.
 * One Employee Fast Food Franchise: Jeremy is the only Mr. Slushy Burger/Dog employee we ever see, aside from the manager and a defected employee.
 * Ugly Guys Hot Daughter: Vanessa clearly takes after her mother.
 * Under the Mistletoe: Baljeet with Wendy Stinglehopper in the Christmas Special.
 * Also, Candace and Jeremy in a music video.
 * The Unfavorite: Dr. Doofenshmirtz, to an absurd degree. It's hinted that Candace might feel this way as well.
 * Unfortunate Name: In the episode The Beak, we get Khaka Peu Peu.
 * Buford's last name is Van Stomm. Roughly translated, and adding an extra M, that is Dutch for "of the stupid."
 * Universal Adaptor Cast: Notably in the Time Shift episodes and "The Monster of Phineas-n-Ferbenstein".
 * The Un-Reveal: In "Vanessassary Roughness" we learn that "Ferb" is short for...
 * Taken Up to Eleven in "Summer Belongs to You" when it turns out Candace doesn't even know.
 * Also, in "The Great Indoors", why Jeremy likes Candace.
 * Unrequited Love Lasts Forever: Isabella to Phineas, whose crush on him has as of yet not wavered in the slightest. (Well, it did once in "The Beak", but it was back to normal by the end.)
 * Unusually Uninteresting Sight: Some of the delivery guys parody this with the "Aren't you a little young..." gag, but the citizens of Danville don't seem particularly surprised when, say, a rollercoaster spanning the entire city shows up out of the blue. In particular (though it's completely understandable, being a secret agent platypus and all) Perry's deadpan reaction to seeing the boys (and Lawrence) fly by on their living room floor (in itself, a Shout-Out to Aladdin) was marvelous.
 * Just about every citizen of Danville, major or minor, lives this trope in spades, to the point where it would take something as dangerous as an enormous swarm of armed robots attacking everybody in order to faze them. (And even then some of them didn't mind. "It's okay, it's a rental!")
 * Up to Eleven: Almost everything the kids do. This leads to Hilarity Ensues when the boys try this in areas where it doesn't work, such as trying to create a romantic atmosphere by dumping an entire box of flower petals on the scene at once (sometimes including the box as well).
 * Almost any trope than can be applied generally to the show that can also be applied to "Summer Belongs to You" got the volume cranked up.
 * Urine Trouble: Suzy's poodle to Candace.
 * Vague Age: All of the main characters (minus Candace) are described by Word of God as "under 15".
 * Verbal Backpedaling: In 'Phineas and Ferb's Musical Cliptastic Countdown', when Dr. Doofenshmirtz realizes his spiel about his MIND-CONTROL-INATOR was caught on-camera, he quickly says, "I meant, 'Mimes control my gator!'" Cut to two mimes and an alligator.
 * Verbal Tic: Captain Bob Webber, the lifeguard. He has a habit of saying "*snaps fingers* Okay!" and he doesn't even seem to realize it. *Snaps* Ok!

""What, you're just going to stand there like a dead fish? I'm giving you a chance to do something here! Honestly, this used to be more fun.""
 * He also does it after someone says "Okay?" Even from afar.
 * Khaka Peü Peü also has one, thank you very much!
 * Very Special Episode: Parodied in "Tip of the Day".
 * Victorious Childhood Friend: Candace and Jeremy, though they met at a later age (11) than most examples. Implied with Isabella and either Phineas or Ferb in "Quantum Bungaloo".
 * Word of God from Povenmire says that its with Phineas. What's unknown is if it happens on or offscreen.
 * Victory Is Boring: Candace goes through this when she realizes she misses her brothers in "Phineas and Ferb Get Busted!"
 * Plus "The Greatest Lazy Day Ever", where the boys decide to do nothing all day, and Candace can't stand it.
 * In "S'Winter", when Doofenshirmtz traps Perry in quick-hardening chocolate, he complains that he's not responding to his gloating, or trying to stop him. He even extends the countdown before firing his laser to give him more time.

"Poofenplotz: It's important to look your very best when you're doing your very worst / And by that I mean evil."
 * Viewers are Morons: The feedback the creators got from Hollywood when they were pitching the series was that it was too smart for a kids' show.
 * This is particularly funny when Jeff talked about some fans he met who said that the show was "smart". Deservedly, they got a little choked up about it (point starts at 8:58).
 * Vile Villain Saccharine Show: The Drill Sergeant Nasty from "Phineas and Ferb Get Busted".
 * Villain Episode: "Hail Doofania!" was inverted from the norm in just about every way the creators could come up with.
 * Villain Song: Doofenshirmtz has quite a few including "Impress My Professor", "My Goody-Two-Shoes Brother" and "Evil Love".
 * Professor Poofenplotz has a short one.

""Look, Perry the Platypus, just because I'm evil doesn't mean everything I do is evil!""
 * Villains Out Shopping: Literally in "Unfair Science Fair Redux".
 * Besides the literal example, he does many other un-evil-relevant things in his spare time. He even lampshades this in "The Ballad of Badbeard":

"Phineas: Pilot's instruments? *looks at the cockpit controls* Check. Co-pilot's instruments? Ferb: *in front of several musical instruments* Check."
 * Villain With an F In Evil: Doofenshmirtz, to a hilarious degree.
 * Visible Invisibility: Steve the Chameleon, who seems only to appear on one episode—so far.
 * Visit by Divorced Dad: Inverted with Doofenshmirtz, since his daughter comes to live with him on some weekends. Completely averted with Phineas and Ferb's respective missing parents.
 * Visual Pun: Candace admires the way the boys have fitted out her old tree house with all mod cons, and says "And look at all the bells and whistles!", passing by a wall with bells and whistles mounted on it.
 * In "Summer Belongs to You!" and "Ladies and Gentlemen: Meet Max Modem!", Phineas and Doofenshmirtz, respectively, deliver speeches about their intentions on boxes marked 'soap'.
 * In "De Plane! De Plane!":

""You monster! Now I'm wet!""
 * "Voyage to the Bottom of Buford" shows Buford's origins as a bully. The first guy he beats up finishes the fight pinned to a literal clothesline.
 * Vitriolic Best Buds: Buford and Baljeet, hands down. They even have an entire song about it.
 * Vocal Dissonance: Meap, when using any of his universal translator mustaches to speak English, has an unexpectedly deep voice.
 * This has also been done as a gag with Candace, Isabella, and Gretchen. In Candace's case her allergy to wild parsnip alters her voice, but the other two appear to be able to do it intentionally.
 * Vocal Evolution: Phineas. Just listen to how he sounds in the pilot and the title sequence, and compare it to the rest of the series.
 * Jenny, on the other hand, seems to be suffering vocal decay; in some of more recent appearances, she sounds like she has a cold.
 * Irving's voice also seems to have gone slightly lower in "Not Phineas and Ferb".
 * Voices Are Mental: When Candace speaks from Perry's body it sounds perfectly normal to her mom.
 * Vomit Discretion Shot: Happens to Candace in "Does This Duckbill Make Me Look Fat?" when she finds out she's been eating worms and insect larvae.
 * Voodoo Shark: In "Buford Confidential", we are given the reason why Buford knows how to speak French: He learned it because he was once in love with a French girl. He then says it was pretty easy, because he knew Latin beforehand. This is, of course, lampshaded.
 * Watch Out for That Tree: In "Run, Candace, Run".
 * Watching the Sunset: "No you're not!"
 * Wave of Babies: Doofenshmirtz attempted to do this in "The Baljeatles", but he failed before even acquiring one baby.
 * Weaksauce Weakness: Sergei the Snail is invulnerable to regular methods of trapping agents due to its small size and adhesive slime, but, being a snail, can be captured by a ring of salt.
 * Meap's species can be immobilized if they see anything that is cuter than themselves.
 * Arguable; considering how Phineas was immobilized as well and that it was implied that all of the other kids were in danger of the same thing, it comes off more that anything too much cuter than the typical example of Meap's race can overpower anything by sheer way of cuteness.
 * Wearing a Flag on Your Head: Ferb rocks out in style in his Union Jack t-shirt in "The Bajeetles".
 * And on his skateboard and in other places. It's as if - with the rarely heard accent - the writers are scared we might forget he's British.
 * Weather Control Machine: The Gloominator3000...inator.
 * We Can Rule Together: Doofenshmirtz tries to zap Perry with his Turn-Everything-Evil-Inator.
 * Weirdness Magnet: Candace, to an insane and unfortunate degree.
 * Inverted by Linda, who's what yo might call a weirdness repellent. She is possibly the only person in the world who doesn't know about Phineas and Ferb's inventions and adventures.
 * We Want Our Jerk Back: Even ridiculously-tolerant Phineas is annoyed by Buford being a total crybaby in "Voyage to the Bottom of Buford".
 * Wham! Episode: For the shippers, the hour-long special "Summer Belongs to You!" as
 * What Could Possibly Go Wrong?: Said almost word-for-word by Stacy in "Moon Farm", before they cook a dish of lamb cobbler for fifteen minutes at 9000 degrees. Subverted in the sense that
 * What Do You Mean It's Not Awesome?: A Crowd Song, and indeed entire episode, about aglets, and that's just the tip of the iceberg.
 * One whole episode was spent playing on those kiddie rides by stores you can ride for a quarter. Much more awesome than it sounds.
 * In "Candace Gets Busted", the partygoers get overexcited watching Phineas and Ferb just sit on the couch eating potato chips.
 * "Make Play" begins with Lawrence describing a jukebox. He greatly overromanticizes it a tad.
 * Meatloaf. Not only was Linda crowned the 'Meatloaf Queen', but, apparently, Danville has an annual meatloaf festival (with meatloaf themed rides, a bounce house and 32 varieties of meatloaf flavored ice cream.) Candace brushes it off as stupid until her favorite band starts singing about how they love the stuff.
 * Carl driving an ice cream truck to distract Buford and Baljeet (so that Perry can leave for his mission).
 * The entirety of Carl's theme song.
 * Perry's Hat. It's Exactly What It Says on the Tin: An entire song about Perry's trademark fedora.
 * Not even that: It's a song about its airborne journey through Danville.
 * What Do You Mean It's Not Heinous?: Minor example from "The Beak"

"Old Coot: New Law! If you find any gold it's mine! Crowd: Yay for finding gold being a metaphor for... uh, I think were supposed to take it literally."
 * What Do You Mean Its Not Symbolic: Parodied in "She's The Mayor", where the crowd believes that everything Candace says is some kind of metaphor, even her "busting" obsession. Of course, this was Lampshaded at the end.

"Teens: We all got a platypus controlling us! Doofenshmirtz: No, just me. I'd stop if I was able. I'm not speaking metaphorically, the platypus controlling me is underneath the table."
 * Parodied again in "Brain Drain", in which Dr. Doofenshmirtz at one point gets glued to a turntable and starts an epic freestyle rap about how Perry is controlling his movements using the doctor's own mind control helmet. Of couse, his audience, being a group of teenagers, interpret "there's a platypus controlling me" to mean that there's some kind of authority figure keeping him down.

"Chicka chicka choo-wop Gitchi gitchi goo means I love you"
 * What Happened to the Mouse?: Some of the destruction wreaked by the boys' and Doof's inventions is never repaired by the end of the episode. One of Doofenshmirtz's rayguns destroyed a dam, releasing all the water behind it. Conk, the caveman Phineas and Ferb thawed out and remained until the end of the episode, and the "Candroid" from the end of another was never seen again. And the Ferbot in the garbage truck...
 * Conk has made a number of cameo appearances since, and possibly another brief speaking part.
 * In "Run, Candace, Run", Candace has three things to do at the same time: She has to read to kids at the library, attend Jeremy's family picnic, and do... something involving being half of a horse with Stacy. She spends the episode running back and forth between the library and Jeremy’s picnic. So did she just completely blow off Stacy?
 * Yes, yes she did.
 * What If: "Phineas and Ferb Get Busted"
 * What the Heck Is An Aglet?: The subject of "Tip of the Day", culminating in an in-show awareness concert.
 * What the Hell, Hero?: When Perry ate all of Doofenshmirtz's cheese, sending him back onto the path of evil.
 * Several in The Movie when the boys find out that Perry is a secret agent.
 * Where The Hell Is Danville? In the Tri-State Area, obviously.
 * Within driving distance of Mount Rushmore, referenced on maps to be simultaneously near San Franscisco and somewhere on the east coast, and a supersonic paper airplane's flight away from New York. Yes, that totally narrows it down.
 * Whole-Plot Reference: "The Wizard of Odd" has Candace taking on the Dorothy role.
 * "Excaliferb!" is mostly a parody of "The Princess Bride", with Karl reading the story to a sick Monogram. It does have some Lord of the Rings and Monty Python and the Holy Grail references thrown in, though.
 * Who Writes This Crap?: "Phineas And Ferb's Cliptastic Countdown": Major Monogram asks who is writing their lines. Carl responds "Agent M, sir". Cue a monkey with a fedora on a typerwriter. Dr. Doofenshmirtz then rants about how none of the kids watching the show are going to know what a typewriter is.
 * Wide Eyes and Shrunken Irises: Grandpa Fletcher demonstrates his 'trick knee' with painful consequences.
 * The Wiki Rule: The Phineas and Ferb Wiki. Jeff "Swampy" Marsh is a regular contributor.
 * William Telling: "Picture This" has Buford daring the boys to shoot an apple off his head. In typical Phineas and Ferb fashion, they do—but not as expected.
 * Will They or Won't They?: "Phineas and Ferb's Quantum Boogaloo" raises the question of whether Isabella will marry Phineas
 * With Friends Like These...: Arguably, Buford and Baljeet.
 * Womb Level: "Journey to the Center of Candace".
 * The Wonka: Phineas dressed the part in the 'one hit wonder' episode. Then again he is the unofficial leader of the group
 * Word Salad Lyrics: The boys make a song with meaningless lyrics in the episode "Flop Starz"

"Dance, baby, dance, baby, shake your hips Go down to the pier and get some fish and chips Groove, baby, groove, baby, motivate your limbs Never eat a cactus if you're out of practice"
 * Quite a few songs in the series end up like this. A delicious example is "Dance, Baby" from "Candace Disconnected". The moment the song is sung is random and silly, and the lyrics top it off:

"Lawrence: Let's Check-eth it out! Linda: Check-eth it out? Really? Lawrence: I stand by my Old English."
 * Wouldn't Hit a Girl: Dr. Doofenshmirtz refuses to fight Perry in Candace's body because of this.
 * Averted by Perry in "Nerdy Dancin'". He disposes of the female members of LOVEMUFFIN with the same ammount of force he used on the male members.
 * Write Back to the Future: "It's About Time!"
 * Wrongly Accused: Perry's subplot in "Cheer Up, Candace".
 * He also gets this in the Show Within a Show subplot of "Nerds of a Feather"—specifically, he's been accused of the assassination of Abraham Lincoln.
 * Wrong Genre Savvy: The DVD character commentary for "The Chronicles of Meap" shows that Doof is Genre Savvy and Monogram is Genre Blind when it comes to their "cartoon universe". (Doof thinks it's ridiculous that Monogram doesn't know what a thought balloon is, for example.) However, Monogram is a little more savvy when it comes to tropes in general, as he ends up predicting the outcome of an obvious case of This Is No Time for Knitting, when Doof thinks Candace has picked a really bad time to be playing baseball.
 * Xtreme Kool Letterz: The guys who sing the "Squirrels in My Pants" song are named 2 GuyZ N the Parque on the soundtrack album (yes, they were in the park and there's two of them).
 * Yandere: Suzy Johnson. Due to Unfortunate Implications, one of the squickiest examples ever.
 * Yank the Dog's Chain: In "Chez Platypus", . Especially cruel in that this happens at the very end of the episode, right after the Crowning Love Song Of Awesome.
 * Irving gets one in "Not Phineas and Ferb". He manages to trick his haughty older brother into believing Baljeet and Buford are Phineas and Ferb despite Paper Thin Disguises. When he tries to prove it, though, he's foiled by the fact that the holographic Eiffel Tower they had been using as a fake project has since been replaced by the real Eiffel Tower, making Irving look like the stupid one. Then his brother gives him a wedgie and drags him home.
 * And Candace, of course, gets one pretty much any time it seems like she'll bust her brothers. And, to a lesser extent, Vanessa busting her father.
 * Candace gets a particularly bad one in "Invasion Of The Ferb-Snatchers": Phineas and Ferb are fixing an alien's spacecraft and open an ostentatious launch platform in the backyard. Candace sees this and gets her mother, who even mentions that she can see it...
 * Worst one for Candace yet: in "A Real Boy", Candace SUCCEEDS... then Linda gets zapped by Doof's "Forget-inator" while the boys' device is in the air, then when the boys land, Linda sees again, then is zapped while they're out of sight again ...this repeats a few more times until Candace's post-hypnotic suggestion to forget about busting her brothers kicks in again leaving Linda to wander off right after a final zapping.
 * It even happened to a one-shot character: Professor Ross Efrop in "My Fair Goalie". He came up with the idea of Football X-7, but he was forced into hiding because Britain's anti-palindrome atmosphere at the time, with his name being discovered to be a palindrome. He nearly comes out of hiding when his creation was realized, but was forced back when he found out people still rallied against palindromes.
 * Ye Olde Butchered English: In "The Belly of the Beast":

"Doof: Ah, Perry The Platypus, you are too late! ...Oh, wait. Is it eleven o'clock yet? [checks watch] Now you are too late!"
 * You Are Too Late: Parodied Doofensmirtz, of course ("Gaming The System"):

"Candace: I was a fool! A foooooool!..."
 * You Fool!: At the end of "Invasion of the Ferb Snatchers", Candace once again fails to bust Phineas and Ferb, and she laments her apparent hubris in believing she could succeed in doing so.

""Congratulations, old boy, you're gonna be a -- hey, where's Perry?""
 * Also it echos the last line of the movie she was watching earlier in the episode.
 * You Fail Logic Forever: Doofenshmirtz reason to revive a Dodo was: Dodos are extinct-Dinosaurs are extict-Therefore, Dodos must have been like dinosours!
 * You Go, Girl!: The episode "Got Game?",
 * You Have to Believe Me: Candace is the MASTER of this trope.
 * Your Head Asplode: Isabella in "Summer Belongs to You", in her daydream.
 * Your Tomcat Is Pregnant: Oddly subverted in "Perry Lays an Egg". Perry never actually laid an egg, but Phineas didn't seem to find it odd that his male platypus had seemingly laid one.
