Phineas and Ferb/YMMV

"Linda: Candace, is everything okay? Candace: Oh, everything is just wonderful. Linda: And... Phineas and Ferb? What are they doing? Candace: Oh, such wonderful things."
 * Accidental Innuendo: "Your hotdog is no match for my bratwurst!"
 * "Wow...Heinz Doofenshmirtz is way too hot, we should get out of him."
 * "Well, Ferb, you sure know how to show a girl a good time." (That one is kinda iffy as far as 'accidental' is concerned.)
 * "Oh yeah, Jeremy, nobody makes a corndog like you."
 * "Here comes the BIIIIG FINISH!", followed shortly by "Ohhh that feels good!"
 * In "Candace Gets Busted", the entire neighborhood has an intimate get together in Doof's pants.
 * One fan decided to look a little too far into the scene in "De Plane! De Plane!" when Candace and Jeremy crash into each other in the dried up pool. The results were, reportedly, scarring, though the video has since been taken down.
 * In one brief moment in "Spa Day", we see Candace and Stacy both relaxing in a hot tub. The same hot tub.
 * Perry trying to go through the rubber hose to get into his lair in "Thaddeus and Thor". His movement combined with that noise...Yeah...
 * When Linda calls Candace near the end of "Lawn Gnome Beach Party of Terror!", Candace's practically orgasmic voice really turns the conversation straight to this.

"Phineas: I didn't think it was boring, Ferb."
 * Linda's shocked reaction pretty much clinches it.
 * And as if that wasn't enough, Candace's "No, don't!" reaction after that makes it even worse.
 * Acceptable Political Targets: In one episode taking place in a Bad Future, it is revealed that Moral Guardians essentially destroyed society by going to Knight Templar extremes and eliminating all traces of fun and creativity. Quite a Take That towards them.
 * Alternate Character Interpretation: Irving is sort of a Base Breaker in the fandom; some find him annoying, while others identify with him because he's an Affectionate Parody of the viewers.
 * Phineas: Is he really that naïve, or just better than Isabella at hiding his own burning affections as implied by
 * Some see the show as Candace's visions of madness, rather than about a show about two brothers who build things.
 * Is Candace a Jerkass who deserves all what happens to her for trying to bust her brothers or do we feel sorry about her life where Failure Is the Only Option because she is the only sane girl who realizes that building impossible things in a backyard may end in a very bad way?
 * Some think the O.W.C.A. are a Big Brother analog. Doofenshmirtz can't even go to the park without the agency sending Perry after him! Not to mention they never give Perry any days off or vacations, not even on Christmas.
 * And the Fandom Rejoiced: Meapless in Seattle. It began as a credits gag in the original chronicles of Meap, with a fake trailer that the writers never intended to make, but fans liked it so much they were eventually convinced to make it into a real episode. Then, nearly three years later, it finally premiered. And the fans loved it.
 * Anvilicious: "The F Games"
 * The Flawless Girl plot from "Attack of the 50 Foot Sister".
 * "The Lake Nose Monster". The fact that the beach-goers don't seem to care doesn't change how heavy-handed it is.

"Candace: [while doing the Caramelldansen movements] I have no idea what just happened."
 * The mandatory healthy eating episode was "Candace's Big Day". Interesting in how, if you look at the labels on the "Junkfoodinator", they read "Corn Syrup" (Which Dr. D refers to as "High Fructose Corn Syrup") and "Partially Hydrogenated Coconut Oil", as a bonus for health-nuts out there.
 * Also notable as a "Health Food Episode" that actually makes sense: Doof picks the scheme because he expects everyone to become "overweight and lethargic" as a result of eating only junk food, making it trivial for him to take over. It can also be seen as exactly the kind of plan Doofenshmirtz would come up with.
 * What is also interesting is that Doof grows overweight and lethargic himself from eating health food... dipped in concentrated fat.
 * 'Phineas and Ferb Get Busted', 'Phineas and Ferb Interrupted' and 'Phineas and Ferb's Quantum Boogaloo' are avid over creativity. But then again...
 * Ascended Meme: As the spectacular opening will tell you, Meapless in Seattle.
 * Canderemy.
 * Ass Pull: Like you got no idea. However, it's due to being a mere parody of making machines that would take 100 expert people 1 year to construct, while two kids construct it in 5 minutes. See also Deus Ex Machina.
 * Award Snub: The show has so far lost three times in a row to SpongeBob SquarePants in the Kids Choice Awards. This is obviously ticking some fans off.
 * Base Breaker: Irving's either hilarious or just plain annoying, depending on who you ask. The fact that he only occasionally appears at all helps to keep the fandom from fighting, though.
 * Candace. She has enough fans to be popular, but also many people who see her as The Scrappy.
 * Isabella. Basically, if one does not ship Phinebella, nor find her attractive (Yes, there are people who do), then odds are they will consider her a Purity Sue.
 * Bellisario's Maxim: The writers have repeatedly been asked the "What happened to Phineas and Candace's biological father/Ferb's biological mother" question, and their response is always this. This doesn't stop the fans, though.
 * Beta Couple: Ferb's crush on Vanessa is seen as this to Phineas and Isabella.
 * Better on DVD: Though plenty of entertainment can still be drawn regardless of what order you watch the episodes, watching multiple episodes in a row, especially the earlier ones first, will allow you to understand more of the jokes made in the show, since a huge chunk of it's later humor is based on lampshading and subverting the Running Gags and making Brick Jokes and Continuity Nods to other episodes.
 * Better Than It Sounds
 * Big Lipped Alligator Moment: The popularity of the "Gitchie-Gitchie-Goo" song in "Flop Starz" led the higher ups to decide to make the musical numbers occur Once an Episode. That includes when it really doesn't make any sense to have a musical number whatsoever. The writers do their best of course, but sometimes there's just no way to work a song into the plot of an episode. And yet there's one there anyway.
 * Of course, considering that every freaking song on this show is a nuclear-powered Ear Worm, this is definitely an example of Tropes Are Not Bad.
 * The fact that it doesn't make sense for a song to be there makes it even funnier when there is, anyway. Mexican Jewish Cultural Festival, anyone?
 * "Izzy's Got The Frizzies", relating to the above. A completely unrelated 70's funk number crammed in before the credits of "Robot Rodeo". Strangely enough, that episode already had a song.
 * "Dance, Baby" appears at the end of a perfectly normal conversation between Perry and Doof, and it comes completely out of the blue.
 * The Tokyo song in "Summer Belongs To You". It's even Lampshaded.

"Phineas: I don't know what causes it but it sure helps with clean-up."
 * In-universe, Perry & Doof's interference with the main plot comes out of nowhere from the kids' point of view, but they rarely question it and almost never bring it up after the fact.

"Narrator: A long time ago in a studio in Burbank, California. A ragtag group of animators made a fake trailer for a Meap sequel they never intended to make. Unfortunately, everyone wanted to see that episode so the animators were forced to write it and incorporate all these seemingly unrelated scenes. I guess the joke was on them."
 * "Phineas' Birthday Clip-o-rama" actually shows a montage of Big Lipped Alligator Moments (courtesy of Baljeet), some of which don't come from any actual episode and are impossible to imagine making sense in any context.
 * Speaking of which, "Phineas' Birthday Clip-O-Rama" is littered with clips of events that never actually occur in the series, such as Perry entering his lair as a giant and getting trapped in a metal shell shaped exactly like himself, pose and all, Doofenshmirtz's Blow-Itself-Up-Inator and Inside-Out-Inator, Candace calling for Mom while she and everything around her looks like an abstract painting, a project of Phineas and Ferb's that involves a device apparently being powered by chickens, and, of course, Evil Lawrence and Evil Linda.
 * Canon Fodder: Oh boy, "Who is Phineas and Candace's biological father, who is Ferb's biological mother, what happened to them and where are they now?" If there was an earthquake for every fic written related to this, the world would be over in minutes.
 * Cargo Ship: Candace and her Ducky Momo doll.
 * Crack Pairing: So many of them get thought up on the Phineas and Ferb Wiki. The constant preferences of nonsensical pairings like Baljeet/Linda and Katie/Doof drives people mad.
 * Crazy Awesome: Phineas and Ferb's schemes, Candace in full flight.
 * Crosses the Line Twice: For an animated program on Disney Channel, this happens with startling regularity— mostly in Harmless Villain Doofenshmirtz's Imagine Spots. An obvious example is the time he planned to found a college of Evilology and, among the projects, the audience was shown the (smoking) skeletal remains of an infant. Another can be found in the episode where he planned to use a space laser (inator) to destroy stuff. Including morning talk show hosts. After (theoretically) using it, the host's arms are still intact, clutching at his mug of coffee. The rest of him is nowhere to be seen.
 * Crowning Music of Awesome: Too many to list, yet we still did it.
 * Deconstruction: "The Curse of Candace" really messed with the idea that being a vampire is cool. Especially the song.
 * Die for Our Ship: Candace/Jeremy shippers don't like Suzy because she doesn't want the two to be together.
 * If you look it in a squicky way, Suzy might have this attitude toward Candace in relations to her brother...
 * Dude, Not Funny: Professor Ross Efrop's Yank the Dog's Chain moment at the end of "My Fair Goalie".
 * Some fans didn't take the "Three guys from Kenya" joke in "The Curse of Candace" well.
 * Ear Worm: Have fun. This goes so far as for earworms to be referenced, with Doofenshmirtz saying "Great, now I have this song stuck in my head" upon hearing 'Perry the Teenage Girl'.
 * Heck, he makes a song that is scientifically created to be stuck in your head FOREVER! "His name is Doof, and we'll do what he says. Whoop whoop!"
 * Ducky Mo, Ducky Momo / He's your very best friend!
 * "Doofenshmirtz Evil Incorporated!"
 * E-V-I-L B-O-Y-S!
 * Ensemble Darkhorse: With the fanbase the size as it is, a case can be made for most (if not all) secondary characters, with the Fireside Girls (Gretchen in particular, since some fans pair her with Ferb) being the most prominent examples.
 * Eliza Beckham Fletcher, it is unlikely she will show up again yet she already got a sizable fanbase following less than 2 days after the one episode in which she does aired.
 * Vanessa Doofenshmirtz also has a huge fanbase.
 * Epileptic Trees: A lot of fans were once convinced that Heinz Doofenshmirtz is Phineas and Candace's biological father, to the point where the creators themselves had to step in and give it the boot. Despite this, many fans still believe this theory to be true.
 * Every One Remembers the Stripper: All anybody seems to remember about the episode "A Real Boy" is the backup singers in the eponymous song.
 * Evil Is Sexy: Vanessa, although not technically evil (according to her, anyway).
 * She is eviler than almost all the cast, what with her stealing a Vespa, threatening people with a faux deadly weapon, and snatching a doll from a little girl.
 * Fandom Nod: In "What a Croc" the fan ship of Ferb/Gretchen got a brief nod after three nearly three seasons of extremely minimal interaction between the two characters. Although the nod itself was very brief, featuring both sharing a jetski after showing Phineas and Isabella quite happily doing the same.
 * Fan Dumb: "The Chronicles of Meap" ended with a joke teaser trailer for "Meapless in Seattle"; this was a part of the shtick that the episode was an episode of The Chronicles of Meap entitled "More Than Meaps the Eye", and satirized action/thriller trailers. Some fans saw this and thought it was a real trailer, and demanded it to be made, causing the once Crowning Moment of Funny to stop being a joke and start being more like Hilarious in Hindsight when the creators yielded and made it. Opinions vary, though, on how much some fans not getting that it was a joke really affected the episode actually being made.
 * And now that the episode is out, we see that this is spoofed hilariously in the opening.

"Doofenshmirtz: You know, Perry the Platypus, that dress sort of suits you... you know, you just accentuate the positive, as they say... Um... I'm going to stop talking now, I'm moving into a weird area."
 * Fan-Preferred Couple: Ferb and Gretchen has become popular with those who have a hard time overlooking the age gap between Ferb and Vanessa (but have an easy time overlooking the fact that Ferb and Gretchen have hardly interacted at all in the show itself).
 * Fanon Discontinuity: Quite a few fans like to pretend that the  ending of Phineas and Ferb The Movie: Across the 2nd Dimension never happened. Not necessarily because they hate it, but because not doing so would prevent a lot of Fan Fiction ideas.
 * Foe Yay: Doofenshmirtz and Perry seems to be a parody of this, with their interactions being explicitly treated like a romantic relationship at least half of the time.
 * "It's About Time!" was just full of Foe Yay, with Doofenshmirtz getting a new nemesis actually presented as an affair. Perry was heartbroken.
 * You know they had the fans of that pairing just squealing over that moment, during "Swiss Family Phineas", where Perry and Doofenshmirtz get thrown in the 'BIG' laundry... cue costume change, with a wedding dress and tuxedo. Just guess who's in the dress.
 * And in "Gaming the System", after Doofenshmirtz zaps Perry with the Ball-Gown-inator, he can't stop going on about how elegant Perry looks.


 * In "Nerds of a Feather" after Doofenshmirtz fails to get his show "Doof and Puss" on the air because he wouldn't let the producer give the platypus a girlfriend, we instead get the show "The Platypus And His Girlfriend", with the girlfriend seeming to play the same role as Doof did in the original show.
 * Baljeet and Buford also get their fair share of Foe Yay as well. "Bully Bromance Breakup" essentially throws all subtext out the window.
 * Funny Aneurysm Moment: In "Summer Belongs to You", Doofenshmirtz's evil plan is to drop a giant water balloon on Tokyo to flood out the Annual Good-Guy Convention. This was almost a year before the infamous quake in Japan that caused massive flooding.
 * Genius Bonus: By the bucketful. In fact, the show's excessive use of "smart" humor was one of the reasons it took so long to get it on the air in the first place.
 * Germans Love David Hasselhoff: Jerry Lewis' popularity in France is referenced twice in "Run Away Runway". Also, Phineas and Ferb The Movie: Across the 2nd Dimension will be shown in theaters in The Netherlands and Belgium.
 * Growing the Beard: Somewhat expected, considering a lot of the show's humor and wit come from lampooning, subverting and Lampshading the conventions and practices that would take a few episodes to establish.
 * Although, in terms of quality though people could spot differences from other shows at the time beforehand, it was Phineas and Ferb Get Busted that arguably showed us just what this show was truly capable of.
 * Hell Is That Noise: Baljeet's "Fail Wail" in The Baljeatles. Seriously, the sound makes you think of some kind of animal, likely a cat, in very severe pain. Even Phineas couldn't stand it.
 * Hilarious in Hindsight: If you remember a certain Crowning Moment of Funny from Justice League Unlimited, the aglet craze in "Tip of the Day" becomes a million and six times funnier.
 * Cheer Up Candace featured the "Mix 'n' Mingler", a machine used to introduce Candace to random new people every few seconds. Among these people included some...less than desirables such as a man who likes to take off his pants. The episode first aired in October 2009, about a month before the creation of Chatroulette.
 * Doofania, which featured, among other things, banners with Doof's name or "Evil" printed on them. In this case, there were only a few, but guess what are scattered around the other Danville.
 * Ho Yay: Doof and Perry of course (it's half of their schtick,) but also Irving and the boys, Buford and Baljeet, Major Monogram and Carl. Enough to make a page for it.
 * Les Yay: Candace and Stacy. Particular examples include "Canderemy" and "Put That Putter Away", where they end up in bed together.
 * There's a bit between Candace and Vanessa too.
 * Candace and Eliza
 * Internet Backdraft: Do not, I repeat, do not bring up the subject of SpongeBob SquarePants around the fans. It gets ugly.
 * It's the Same, Now It Sucks: "It's too repetitive" is probably the most common complaint people who dislike the show give, though later seasons have been playing with the show's episode formula quite a bit, so this isn't holding up as well as it was before.
 * Launcher of a Thousand Ships: Ferb, Baljeet, and Doof, in particular.
 * Less Disturbing in Context: Near the ending of "That Sinking Feeling" Baljeet says to his friend Mishti "So you are telling me that even though you are now a girl, you still like to have fun just like in the old days?". If one has not seen the opening scene of this episode, that line can come off as incredibly disturbing, for obvious reasons.
 * Marty Stu: Phineas tends to be able to do anything without repercussions of any kind. One example of Tropes Are Not Bad, though, as this does not seem to make him less likable as a result, and there have been instances where this trait of his has been averted. (The Dream Within a Dream sequence where he finally gets busted springs to mind).
 * This has been played down in later episodes, with Phineas being better developed as a character, along with Ferb to a lesser extent.
 * Memetic Badass: Perry's a semi-aquatic egg laying mammal of action!
 * Memetic Mutation: It's a rather meme-rich show, and they're collected over on our meme-page-inator.
 * Memetic Outfit: Phineas and Ferb's signature outfits, as lampshaded in one episode when whey went back-to-school shopping.
 * Memetic Sex God: Ferb. Yes, he's only ten-ish, but that doesn't stop the fangirls from getting all over him.
 * Moe: Isabella when she makes the effort.
 * As can Phineas.
 * Perry while in pet mode can also count, especially when he's sleeping.
 * And when he's a baby.
 * Moral Event Horizon: In "Phineas and Ferb's Quantum Boogaloo", the Knight Templar Moral Guardians outlaw all fun and creativity. While that could be fairly easily chalked up to being Well-Intentioned Extremist, stuffing their own children into tiny capsules until adulthood is just plain sickening, no matter what the intent.
 * Parallel Doofenshmirtz from The Movie crosses this when he tries to kill Perry, Phineas, Ferb, Candace and normal Doofenshmirtz via a lava-filled death trap. Though he was kind of already halfway there since he
 * Doofensmirtz's parents cross it in his backstories a lot. Often Crossing The Line Twice.
 * Most Wonderful Sound: "Hey Ferb, I know what we're going to do today."
 * Ctrtrtrtrtrtrtrtrtr
 * Doofenshmirtz Evil Incorporateeeeeeed!
 * Nausea Fuel: In "Hide and Seek", . This probably makes for good Nightmare Fuel, too.
 * "I DID WHAT I HAD TO DO TO SURVIVE!"
 * Justified by
 * Baljeet's brain in "Cranius Maximus". It's basically swollen up to the point where it's larger than the rest of his head and barely staying inside his skin.
 * Never Live It Down: Fans seem pointedly fixated on the one time Phineas has ever yelled at anybody (Candace in "Summer Belongs to You"). Case in point, look how frequently it comes up on these pages.
 * Based on this wiki, fans seem to have latched on to Charlene's one-time statement of "No one's evil," taking it absolutely literally as evidence that she's hopelessly naive, rather than accepting it as a simple sweeping generalization meant to dissuade that silly notion of Vanessa's that her father's evil.
 * Nightmare Fuel:
 * The "Smile Away" reformatory school from "Phineas And Ferb Get Busted!".
 * "Monster from the Id". If Baljeet didn't unplug the machine in time... And for more Fridge Horror, by the end of the episode,
 * Escape From Phineas Tower.
 * The end of "Canderemy", where Phineas and Ferb become fused into a single being.
 * No Yay: Suzy's relationship with Jeremy gives of serious Yandere vibes.
 * Also, at the end of "Monster from the Id", we get Buford quite obviously flirting with Candace's Id. No, not Candace, her Id. As in, an anthropomorphic part of her psyche.
 * Older Than They Think: Buford's character in the parody of The Wizard of Oz is an amalgamation of a lion, a tiger, and a bear (oh my). Few fans seem to realize that the writers of Phineas and Ferb didn't make this up. It's a creature from the Wizard of Oz novel that was left out of the film (called a Kalidah).
 * Periphery Demographic: It's a Disney Channel show with an 8-14 primary demographic. Don't be surprised at how many people fall out of that range... including Shawn Spencer and Jon Stewart.
 * "Aren't you a little old to be watching Phineas and Ferb?" Yes, yes I am.
 * To put this in perspective: Sluggy Freelance of all places used an obscure Shout-Out to the show.
 * Also notable to be one of the few Disney Channel shows that Cracked.com likes, according to its topic page about the series.
 * The fact that it is a Disney channel show that has had 2AM reruns says something about how many adults watch it.
 * Hell, even Yu-Gi-Oh!: The Abridged Series referenced it in Episode 53. Says something if Seto Kaiba can instantly recognize a P&F reference.
 * Looks like we can add Slash to the list who liked it enough to co-write an insanely epic song for the movie.
 * Portmanteau Couple Name: Phinbella and Canderemy.
 * The latter which was the title of an episode.
 * Ferbnessa for Ferb and Vanessa and Ferbtchen or Fretchen for Ferb and Gretchen.
 * Phinerb for Phineas and Ferb
 * Perryshmirtz!
 * Parl, Carl and Perry.
 * Baljinger for Baljeet & Ginger.
 * Bujeet, or less commonly, Balford.
 * Baljinda also exists for some reason.
 * Relationship Sue: Jeremy is probably the most tolerant, compassionate boyfriend in existence, what with the crazy ranting and screaming Candace is prone to. His Sue-ishness was more apparent in the earlier episodes. More recently, he has improved quite a bit.
 * Ruined FOREVER: This was how a lot of fans reacted to the news that the 2013 film was going to have Roger Rabbit Effect in it. And the film's plot hadn't even been released at that point.
 * Scare'Em Straight: Smile Away Reformatory School from "Phineas and Ferb Get Busted"
 * The Scrappy: Irving, but more recent appearances have redeemed him in some viewers eyes. Suzy was also one once due to how relentlessly cruel (and creepy) she was, but she has since gained a bit of Character Development and become somewhat less divisive. Some consider Baljeet The Scrappy, since he's a one-joke character and an ethnic stereotype.
 * Seasonal Rot: Some fans of the show think that the quality has been going downhill during Season 3, though some believe otherwise.
 * More accurately, the episodes from the middle of the third season just haven't been as good as episodes from the second season and the first half of the third. That said, the show is still quite good - as far as Seasonal Rot goes, P&F manages to get off pretty easy, what with the show still being of a pretty good quality, even if it'll never be as good as it was from Dude We're Getting the Band Back Together up until the Big Damn Movie. (Which it might)
 * Ship Mates: A good portion of Phineas/Isabella shippers will just pair off the rest of the boys/girls in the group. The most common ones are Ferb/Gretchen, Baljeet/Ginger, Buford/Adyson, Django/Milly, and Irving/Katie. Notice how they don't take Ferb's Precocious Crush on Vanessa into account.
 * Phineas/Ferb fans will almost always ship Jeremy/Candace.
 * And to a much lesser extent Ferb/Isabella and Phineas/Django.
 * Signature Scene: "Get on the trike!" is easily the most remembered part of "Summer Belongs to You".
 * Special Effects Failure: Usually when a Photoshopped object or background appears. Sometimes played as Stylistic Suck, other times not.
 * Squick: Baljeet hiding inside the corpse of a fly in "Hide and Seek".
 * Candace saying "Barf-a-roni with cheese!"
 * Wicked fans could find Doofenshmirtz and Baljeet's parody characters in "The Wizard of Odd" particularly Squicky, considering that they are the Wicked Witch of the West and the Scarecrow, respectively. (Though the episode was based on the original book and the Judy Garland film.)
 * Probably played for laughs, but the skin on Ferb's face slipping off like a hood as he rides a spaceship (followed by him pulling it back onto his skull without any ill effects).
 * Isabella may be cute, but some people find her obsessive stalking crush on Phineas very creepy.
 * The way the red rubber boots in "Wizard of Odd" have (literally) "grown on" Candace's legs looks rather squicky.
 * Stoic Woobie: Ferb can be this at times.
 * Straw Man Has a Point: The "Give Up"-song: Candace gives up trying to bust her brothers (though Comically Missing the Point her aunt was making), only for her aunt to convince her to never give up. While "never give up" is usually a good Aesop, when Candace gave up she stopped stressing out and relaxed.
 * Tastes Like Diabetes: Bango-Ru, especially its convention.
 * "Ducky Momo" appears the be this universe's equivalent to Barney the Dinosaur and other such sugary-sweet toddler shows, which is probably why Candace catches so much grief for liking it (or believes she would).
 * Jeremy and the Incidental's song from "The Best Lazy Day Ever".
 * Isabella's pony from "The Magnificent Few" (start at 5:12).
 * Meap's Planet. According to him, cuteness is valued above all other things on that place.
 * Tear Jerker: See here.
 * They Wasted a Perfectly Good Character: Django. A sort of Sixth Ranger to the main group, he even got a full episode focused on him (Oil On Candace) in the first season. Nowadays, he's been overshadowed by Irving and really only appears in cameos.
 * It doesn't help that was kinda bland. Or at least, he didn't have a single defining trait like most of the main cast do.
 * Well, he was good at art.
 * Toy Ship: Multiple. The most prominent of these would be Phineas and Isabella.
 * Baljeet and his friend Mishti in "That Sinking Feeling". We'll probably never see her again, though.
 * Some fans also like to ship Ferb with Gretchen (the Fireside Girl who wears glasses).
 * Baljeet and Buford deserve a mention.
 * It should be noted, though, that P&F is only a partial example, as all the characters are canonically "Under 15".
 * Ugly Cute: Heinz Doofenshmirtz. He's a hunchback with crooked teeth, a long nose and crazy hair and has even admitted on screen that he's ugly, but he's still completely adorable.
 * Also, Doof's giant pet cockroach from Canderemy. Awwwwww.....
 * Even Buford could count as well.
 * Uncanny Valley: Balloony. Just look at him.
 * The Best Live Tour Ever!.
 * Unfortunate Implications: Suzy's feelings for Jeremy, while Played for Laughs, would be indicative of something very serious in real life.
 * In We Call It Maze, the girls seem to have consistently gotten the physical challenges while the boys got the mental ones.
 * Of course, in this case the boys's group contained Phineas, Ferb, and Baljeet. Not so much a case of boys being smarter than girls as these particular boys being smarter than pretty much everyone.
 * "Summer Belongs to You" sends the message that it's a good idea to jump a bike over a construction site (if it's to win a bet). The show is full of far-fetched dangerous hijinks, but this is one that impressionable young viewers would be able to imitate.
 * In "The Wizard of Odd", Linda basically tells Candace to ignore the advice given to her by a clearly trusted official in favour of the fun way...that she was morally against the whole time and wanted to see "the wizard" for anyway.
 * No mention of Jeremy's "Set the Record Straight" song? The lyrics certainly give off vibes of "a man feeling romantic love for anything that is not a woman is abnormal"...
 * Uh, where did you get that? The most disservice Jeremy did to homosexual relationships in that song is simply not mention them. Which brings up the question: why should a teenage boy trying to serenade his girlfriend be forced to work man-on-man relationships into the song he's using to do it?
 * I think it may be the title...
 * What an Idiot!: In "Candace Disconnected" the boys give Candace a phone with an app that will send her to anywhere she wants just by saying "Go to" followed by the destination. She leaves before they can tell her about the app and then ends up accidentally transported to Easter Island. She just assumes transporting you to Easter Island is the app's one function. Even after being accidentally transported twice, she still hasn't figured out how it happened.
 * Phineas, Ferb, and their friends fail to realize that Candace is wearing a camera in "Leave the Busting to Us," even though she was right in front of them when she put it on and when she talked to the Bust 'Em producer about getting footage of the water slide.
 * Phineas's Oblivious to Love has always been a bit face-palm inducing, but it officially drops to idiot levels in "Summer Belongs to You".
 * Doofenshmirtz...ugh, where do we even begin...
 * The Woobie: The main example is Doof. As a child, he had to throw his surprise birthday party. His father named the dog "Only Son". When he was born, neither of his parents bothered to be there.
 * Candace. One must feel sorry for how hard she has to try to bust her brothers, even if her determination can be irritating to some. Also in "Candace Gets Busted," where she gets punished by her mom for throwing a party that was out of her control and which she legitimately didn't want. But it really comes out in "Nerds Of A Feather".
 * An odd one, but Buford in "Voyage To The Bottom Of Buford". In his song, he was shown to be so lonely he was playing ping-pong with his goldfish!
 * Phineas' obliviousness to love can put Isabella into this territory, especially during her song "City Of Love" in "Summer Belongs To You."
 * Not everyone feels sorry for her, and some even consider it karma.
 * Norm becomes one officially in A Real Boy.
 * Phineas, who is normally unbelieveably cheery and innocent, completely breaks down when things start going wrong. (See Summer Belongs to You, Christmas Vacation, and The Movie.)
