First Season Theme Song

Johhny Test (2005-2013, 2020- ) is an Animated Series featuring the eponymous 11-year-old hero and his "super talking dog", Dukey, and their various crazy exploits thanks to Johnny's older twin sisters' Mad Science. Created by Scott Fellows.

Not to be confused with Jonny Quest. Character sheet found HERE.

Tropes used in Johnny Test include:
  • Absurd Altitude: An amusement park ride meant to deter Johnny from having an amusement park at his house.
  • Accidental Public Confession: The Moonsies do a Type 2 when Johnny and Dukey see their plans to invade the Earth. It's a Type 2, because although Johnny and Dukey see the plans, they don't understand them because they can't read Moonsie.
  • Actor Allusion:
  • A.I. Is a Crapshoot: When Susan and Mary build boy-borgs to make Gil jealous, they become * very* possessive of the twins.
    • Later happens to Johnny's new smartphone in "iJohnny".
    • Pretty much anything that the girls make with A.I. will turn evil save for something that Johnny's supposed to immediately break.
    • Also anything the military makes in Area 51.1, like the look-alike cyborgs in "Johnny Johnny" and the super soldiers in "Johnny X Strikes Back Again".
  • Air Vent Passageway: Lampshaded: "When did your dad install these giant ducts?"
  • Aliens Speaking English: The Vegans from Vegandan. This, of course, is Lampshaded.
  • All Animals Are Dogs: Repto Slicer likes to chase sticks and rubber balls.
  • All CGI Cartoon: Post-Channel Hop.
  • All Just a Dream: Rock-A-Bye Johnny.
  • Alpha Bitch: Janet Nelson Jr.
  • Ambiguously Gay: Dukey has shown a few signs of it. The very first time he was shown, he was wearing biker leather and enjoying it. Also, when he nonchalantly explains male dominance and let's not forget when Susan and Mary brainwashed him in that one episode. One time he was turned into a cheerleader and said that he felt pretty and, of course, Señor Smoothy-Buns.
    • More so Gil. In one episode, Johnny dresses as a girl and Gil doesn't notice him. He stated once how he didn't like cookies but loved Johnny. He only really pays attention to Johnny and not really anything else.
      • Actually he seems to be bi. In the sleepover episode he chases after Jilian, the "hot green haired girl", much to Susan's dismay.
        • Gil really doesn't have many stereotypically gay mannerisms like Dukey has, though.
    • The Mole People.
  • And Zoidberg

Hugh Test: I have such brilliant children! And Johnny.

  • Animal Superheroes: Super Dukey.
  • Animal Talk: Dukey can speak to animals regardless of what species they are.
  • Anime Hair: Johnny himself of course.
  • Archived Army: Johnny brought back several historical figures, including Attila the Hun and a caveman, to create the most powerful hockey team.
  • Art Evolution: Season 1 is significantly different compared to the rest of the series.
    • Which is due to switching from traditional animation to Flash. The first season was animated at Warner Bros. But budget cuts from the merger of the CW and the WB forced the animators to a new studio (Cookie Jar Entertainment) and format for the second season.
  • Aside Glance: After Dukey shouts "I LET YOU RIDE ME LIKE A HORSE!", Johnny gives the audience one of these.
  • Attractive Bent Gender
  • Author Appeal: Gender-bending and crossdressing (usually of the male-to-female kind) play huge roles in many episodes.
  • Batman Gambit: A trap set by Dukey to capture Johnny's Evil Twin requires that the Good Twin reveal the trap to the evil one and the Evil Twin step contemptuously over the trigger.
  • Blackmail: No, not Mr. White. Johnny does this to his sisters if they don't need a favor, but he wants something from them.
  • Blatant Lies: Dukey is "a kid with a rare hair disorder".
    • "Did I say I was eleven? I meant... eighteen!"
  • Blah Blah Blah: Johnny does this quite a lot.
  • Bee-Bee Gun: The Bee Keeper.
  • Belligerent Sexual Tension: Between Johnny and Sissy.
  • Be the Ball: Happens to Johnny in the Turbo Time Rewinder episodes. The person doing it evens says the trope's name.
  • Beware the Nice Ones: Dukey.
  • Big Red Button: While controlling a fake monster, Dukey keeps telling Johnny not to push the red buttons they see.
  • Big No: Uttered in quick succession by Susan, who is horrified about the prospect of dating Bling-Bling, Johnny, who is about to be hit by a golden laser, and Dukey, who *really* didn't want to place himself in the way of danger to save Johnny.
  • Bizarro Universe: Johnny and Dukey shrunk down beyond the atomic level and arrived in a reversed Porkbelly.
    • In a later episode they end up in Leadbelly, a genderbent version of Porkbelly where Johnny naturally falls for his female counterpart.
  • Body Horror: Often the result of Mary and Susan's experiments on Johnny.
  • A Boy and His X: Johnny and Dukey, natch.
  • Bread, Eggs, Milk, Squick: A few listings of possible side-effects from tests usually are this.

Mary: ...oooor your head could explode.

  • Broken Glass Penalty: One episode goes through all the variants of this trope when Johnny accidentally ticks off a crazy man in one episode, and goes through a variety of competely pointless and ever more complex plots to try and get the ball back.
  • Brother-Sister Incest: Mary gives Johnny quite an infatuated look after they make him into a pheromone ridden stud magnet. "You really are adorable, Johnny."
  • Butt Monkey: Susan, at times.
    • Eugene (Bling-Bling Boy) is this ALL THE TIME.
    • Poor, poor Dukey gets it the worst of all of them.
  • Calling Your Attacks: Shapeshifting Powers Go!
  • Canada, Eh?: The moon episode and "Johnny Mustache". Also, the series itself is affiliated with Canada.
  • Catch Phrase: Multiple. Includes "Whooooa... Didn't See That Coming", "Ooh, so close," and "Say wha?"
    • Susan and Mary: "We are such geniuses."
    • Everyone in the Test household at one time or another: "To the lab!"
  • Cats Are Mean
  • Changing Clothes Is a Free Action: "Johnny Johhny"
  • Channel Hop: From 4KidsTV (formally Kids WB) to Cartoon Network, made official with the coming of a fourth season.
  • Chekhov's Gun: The incinerator that Janitor!Dukey uses to burn trash throughout the wood shop episode. Guess how they stop the rampaging turbo-wood-bench.
    • Johnny: Incinerator! Coooooool. Can we burn something?
    • Dukey: Maybe later.
  • Child-Hater: Wacko, who is ironically a toymaker for children. The products he usually builds are designed to get them out of his life.
  • City of Adventure: Porkbelly.
  • Clone Degeneration: The reason why robotic clones of Johnny do not obey commands.
  • Continuity Nod: In the episode 'Who's Johnny?', before the final sequence returning Johnny to his original personality, Johnny changes personalities contained in his genetic code every time he gets hit. One personality he gets is of a dog, with the same design when the girls altered his DNA to make him a dog in an early episode.
  • Cowardly Lion: Dukey.
  • Crossdresser: In Episode 41a: "Join the Johnny Scouts", Johnny becomes a Girl Scout and tries to sell 1,000 boxes of cookies to get a new bike. His father is clearly uncomfortable with this and Johnny tells him that "you said you'd love me and accept me no matter what", but he is using this situation to bribe his father into buying the last 37 boxes of cookies.
    • Gil also buys a box of cookies because: "I hate those cookies, but I love you Bro-man!".
      • Not that kind of love. He asks Johnny earlier in the scene what's different about him. Johnny deadpans "I'm a girl.", and Gil goes "Nooo, that's not it."
    • He also does it in "Take Your Johnny to Work Day" and does so again in "Johnny Dodgeball", albeit that time it was reluctantly.
    • Also in the episode where Mr. Mittens was introduced and Johnny and Dukey were tricked into it.
    • Not that other characters don't do it too. Let's see, Dukey's done it, Gil's done it, Mr. Black's done it, etc...
  • Deadpan Snarker: Dukey, Jillian.
  • Demoted to Extra: Janet Nelson Junior was Johnny's supposed Love Interests in the first season until Sissy Blakely came along. Last seen as a background character.
  • Deliberately Monochrome: "Johnny Swellville" when Johnny and Dukey are in the 50s.
  • Dick Dastardly Stops to Cheat: Brain Freezer in the Wacky Racing episode. His racing partner asks why they are doing this when their car is literally the fastest one in the race.
  • Did Do the Research: The first Tinymon episode actually grasped a lot of Pokémon's mechanics:
    • Cuddlebun = Magikarp Power.
    • Evolving by happiness.
    • Screechereen is a combination of Lugia, the legendary birds, Gyarados, Mew (may or may not exist), Missingno (may or may not exist), and Pikablu, Nidogod, etc. (may or may not exist). Also, in general, flying Pokémon are superior for some reason.
    • Stealing Tinymon.
    • The second Tinymon episode contains reference to Digimon, with de-evolving and Jogress.
    • Oddly, they Did Not Do the Research with chess, a game everyone knows how to play.
  • Did Not Do the Research: The episode where Johnny is transported into a Speed McCool movie has him later going to a movie with no romance... he chooses a Star Wars-esque movie... yeah, apparently Han & Leia in the original trilogy and Anakin & Padme in the prequels doesn't count.
    • De-evolution in the second Tinymon episode. De-Evolution is from Digimon, not Pokemon.
    • I doubt Tinymon is just a parody of Pokemon. Note that it has "mon", so it could include Digimon. They're just making a parody of Pokemon, not ripping off it entirely.
  • Didn't See That Coming: Parodied in the form of a Running Gag. You can hear the line in almost every toon, usually after some form of "plot twist."
  • Disappeared Dad: Not once has Bling Bling's dad been mentioned.
  • Distaff Counterpart: The whole show, to Dexter's Laboratory. Red-haired geniuses, blonde sibling breaking experiments, etc. Even the parents on both shows somehow look alike, especially the dad.
    • This could be because Chris Savino, who was the main director for seasons 3 and 4 of Dexter's Laboratory, worked on Johnny Test.
  • The Ditz: Johnny.
  • The Drag Along: Dukey.
  • Dude, She's Like, in a Coma: Susan and Mary want Johnny to invite Gil over for a sleepover so that they can kiss him while he sleeps. Bling Bling insists that Johnny invite him as well so he can kiss Susan while she sleeps.
  • Dumb Blonde: Johnny and Gil.
  • Episode Title Card
  • Even Evil Has Standards: When Zizrar plots to steal the Porkbelly Library, he send the authorities a letter warning them about what he's doing after the setup is complete because although he wants to make the humans stupid, he doesn't want to hurt anybody.
  • "Everybody Laughs" Ending: A number of episodes, but the third season ending is notable for the villain of the piece joining in the laughter until he lampshades it. Then he swears revenge.
  • Everything Is Better With Penguins: Subverted as the penguins in one episode start taking over the world due to global warming
  • Everything's Worse with Bees: In the episode, Johnny Bee Good and Johnny Holiday.
  • Evil Laugh - Both Johnny and Susan used one at certain times. A person whom the SSGA is monitoring has one as well.
  • Expository Theme Tune
  • Expy: A parody of Fred appears in an episode involving the characters trying to find instant fame from posting videos online like him after seeing him become rich and get a movie. In the end they see the character's movie is terrible because its only gimmick was he had a squeaky voice.
  • Face Palm: Dukey does this. A lot.
  • Feminine Women Can Cook: In the episode "Johnny Daddy Day", it is shown that Johnny's super-busy working mom Lila and genius inventor sisters Mary and Susan have no experience in cooking whatsoever. They aren't even sure what a spatula is or does. Under the guidance of Johnny (who took a cooking class to get an easy A grade), they manage to make a meatloaf for Hugh for Father's Day, only for it to come alive and attack him.

Mary and Susan: We... might have used too much DNA.

  • Flamboyant Gay: Nobeard and his pirate group, as well as the Mole-People.
  • Forgotten Birthday: In the episode "Bath Time for Johnny", Dukey thinks that Johnny forgot his birthday.
  • Four-Fingered Hands: Lampshaded two different times. Once when Susan waved her pinky around when trying to indicate the number four on one hand and other when the General up another finger on the other hand to represent the number three.
  • Freaky Friday Flip: Hugh and Johnny complain that the other has an easier life. To prove it, they switch bodies with Mary and Susan's help. At the end of the episode, after they've learned how hard each others' lives are and switch back, Susan and Lila get into the same fight and switch places as well.
  • Freudian Trio:
    • Johnny: Id (the reckless one)
    • Dukey: Superego (the sane one)
    • Susan & Mary: Ego (the experimenters)
  • Gender Flip: It's been described as "Dexter's Laboratory but with the genders reversed. Also there's a dog."
  • General Ripper: Played for comedy. The General really likes missiles.

Johnny: The military would never fire at us in a heavily-populated area!

  • Genre Savvy: But often too late for Johnny.
    • In "Johnny Get Your Gum", The unnamed (Ambiguously Asian?) female member of Mr. Wacko's (also unnamed) board has apparently read the Evil Overlord List:

Board Lady: You do realize, sir, that you just told Johnny your entire plan?
Mr. Wacko: No matter.
(later, as Johnny and Dukey are in a Death Trap)
Board Lady: Shouldn't you stay, sir, and make sure he doesn't escape?
Mr. Wacko: Real villains never stick around!
 They do escape.

    • When did we land in a bad [decade] [genre] [medium]?
    • When Johnny and Dukey are transported into a fantasy story and called Chosen Ones, Johnny reassures Dukey that they'll win because Chosen Ones always win. Subverted when it turns out to be a simulation and they were playing against Susan and Mary, but he gets points for trying.
    • Johnny in a recent episode. When he wins a cruise in a contest he never entered, he instantly realizes it's probably a trap and comes Crazy Prepared (and, without them knowing, makes sure everyone else was as well). Naturally he was right.
  • Getting Crap Past the Radar: The monster truck episode where Dukey explains male dominance as "hopping on each other".
    • Johnny gets a wart on his hand. His sisters attempt to use a laser to get rid of it. It's about to split him in half when he reminds them that the Wart is on his hand.
    • In the Johnny applesauce song, something along the lines of: The lunch lady tried all her tricks and it made her look like a total * fool*" They obviously meant dick or prick.
    • Or bitch. There's always the obvious one.
    • Dukey has a few of these which is appropriate since his name means something else in slang

Dukey: Come get me, Mole People. I'm full of macho, leathery biker goodness!
Dukey: You're Shitzus, right? I love that name!

    • In the Tinymon episode, there's an extremely powerful Tinymon named Badias (or however you spell it). While it could be reasonably claimed that it was meant to be a parody of the Pokemon Latias, it could be that it was also supposed to stand for "bad-ass," considering how intimidated the other characters were of it. It also helps that it was actually pronounced bad-ee-ass.
    • In Johnny Dukey Doo, Johnny's dad said he and Johnny's mom's first date was at an inn that was scheduled for demolition.
    • In "Hoist the Johnny Roger", the following exchange occurs between Johnny, his dad along with his sisters:

Hugh: Johnny, why can't you be more like your sisters?
Johnny: Well, for starters I have a-

    • In the early episode "Johnny Test: Party Monster", there's this exchange:

Dad: We've finally decided to let you have your first teen dance party...with boys.
Susan and Mary: *sigh* Gil...
Dad: But the lights stay on at all times!


Susan: What does she have that we don't?
Johnny: A gorgeous face, a perfect tan and strong white teeth.
Susan: Hey! We have... strong white teeth!


Johnny: I know I've seen this somewhere before.

  • Large Ham: So many. Johnny, Dukey, Bling Bling Boy, Brain Freezer just to name a few.
  • Law of Disproportionate Response: Dukey dumps large amounts of water onto a neighbor's cats because one of them scratched him the other day. Of course, Dukey's a dog so he feels disliking cats is part of his job.
  • Laser-Guided Karma: To the point where there is an episode about it.
  • Leaning on the Fourth Wall: "I know I've seen this somewhere before!". Said by Johnny in the Scooby Doo and Tom and Jerry-inspired episodes.
  • Sorry I Left the BGM On: Done in "Tom & Johnny", with the home network music player providing the musical background for the Tom and Jerry-inspired antics.
  • Lethal Chef: Hugh Test.
    • If nobody likes his cooking then why is he the only one who does so?
    • Johnny seems to believe 'Mint chip' ice cream is made of Mint, Potatoe chips, rocks and salt (instead of rock salt).
    • In "Johnny Daddy Day", the rest of the Test family manage to become these. (see the Feminine Women Can Cook entry above)
  • Lethal Joke Item: In a fighting game called Sacred Sword IV, there is a Joke Item called the building block sword that Dukey claims is powerful if you know how to use it. Dukey, however, does not. But Johnny, through the course of the ep does figure it out and defeats Sissy Blakely with it.
  • Literal Split Personality: Susan and Mary remove Johnny's negative brain plasma and it grows into an Evil Twin
  • Long Title: The Say-Goodbye-To-Johnny-Blow-Out Bye-Bye-A-Palooza-Jamfest Super-Send-Off Party Jam.
  • Loophole Abuse: In the first episode Dukey points out to Johnny that Hugh told him "touch [his camera] and die", after which Johnny states he's not physically touching it, since he's operating it using a stick.
  • Lost Aesop: "There's a lesson in all this, but darn if I know what it is."
  • Love Makes You Crazy: Mary and Susan, when it comes to Gil. Smartpants when it comes to Johnny.
  • Mad Scientist: Mary and Susan, Bling-Bling Boy, Brain Freezer
  • Made of Explodium: The non-explosive water snake and when racing Johnny through the woods, the stuff Susan and Mary make out of natural things.
  • Mama Bear: Lila Test.
  • Meaningful Name: Hank Anchorman.
  • The Men in Black: Mr. Black & Mr. White.
  • Mid-Battle Tea Break: While "playing" a game of Uncle where each person beats the hell out of the other to get them to say "Uncle", Johnny, Dukey, Susan and Mary stop in the middle to have snacks.
  • Negative Continuity: Averted, as the characters do call back to previous episodes. In fact the third season finale uses this as a plot point.
  • Nerd in Evil's Helmet: Dark Vegan comes off as a parody of this.
  • Never Say "Die": Played straight for the most part, but weirdly averted in "Johnny's Royal Flush" where a gator is heavily implied to have been chopped up in Porkbelly's sewer system and turned into luggage
    • The actual word "die" - not to mention the word "kill" - is averted, however. Johnny's enemies always wants to "destroy" him.
    • What about in "Deep Sea Johnny" when it was implied that the octopus was killed and served as sushi?
    • Also in "Johnny Testosterone" Mary and Susan mention their dad will Kill them if anything bad happened with Johnny.
  • Niche Network: "The Nutz Channel. We're all nuts, all the time."
  • No Celebrities Were Harmed: Bill the Human Guy sounds like William Shatner
  • No Indoor Voice: Seriously. In later seasons, the characters yell frequently. To be fair, would you calm down if the Earth's rotation stopped or a villain tries to turn every creature into cats?
  • Non-Standard Character Design: Speed McCool and his sidekick Monkey look jarringly more realistic than the other characters.
  • Noodle Incident: Several. Occasionally used as Blackmail by Johnny or a reason they can't do an experiment without getting in trouble with Dad. For example, experiments somehow resulted in a gigantic Johnny bursting out of the roof of the Test house and shooting lasers from its eyes...twice.
  • Oblivious to Love: Gil in regards to Mary and Susan.
  • Obviously Evil: One shot character Larius Nefarious. Hell, it's the whole reason the SSGA decide to investigate him. As it turns out, his daughter was the evil one.
  • Once an Episode: "Whoa. Didn't see that coming." Dukey lampshaded this at least once.
  • One-Scene Wonder: She-Johnny appeared for about a second in the very first episode. Now type in female Johnny on Deviant ART, or a related site. Hard to believe that one second appearance can inspire that much fanart.
  • Only Sane Man: Dukey.
  • Overused Running Gag: "Whooooa, didn't see that coming."
  • Packed Hero: Subverted. Johnny and his friends visit an ice cream factory, and Johnny's dog is thought to have fallen into the vat and been packed into a tin. After Johnny eats his way through the entire batch, the dog walks up to him and asks Johnny what he's doing.
  • Painted Tunnel, Real Train: In an episode with Shout Outs to old Road Runner cartoons.
  • Papa Wolf: Hugh Test.
  • Parking Problems: The sisters' van is towed for parking in front of a fire hydrant.
  • The Password Is Always Swordfish: Passwords set by Susan and Mary always include Gil's name.
    • In the episode, Johnny Escape from Bling-Bling Island, the password to one of the locks is "Susan".
    • Apparently Mary and Susan realized this, because in another episode they changed the password(s). Yet Johnny, and even Lila, were able to figure it out, and it still involves Gil.
  • Plot Parallel: Dawg & Bone.
  • Powers as Programs: Johnny's ever-changing mutant powers.
  • Professor Guinea Pig: Johnny, a rare voluntary example, and Dukey, rather less so.
  • Projectile Toast: In one episode Johnny accidentally brings a Crash Bandicoot parody to life, who uses Johnny's toaster to shoot flaming toast.
  • Pstandard Psychic Pstance: Johnny uses this when wearing a helmet designed to telekinetically turn objects into weapons.
  • The Psycho Rangers: The Johnny Stopping Evil Force 5.
  • Punny Name: Mary and Susan... Johnny TEST?
  • Puppy Dog Eyes: Used by Johnny on his family to go to a ski resort. Used by a whole bunch of kids including Johnny on a ski captain but it is subverted when "The Look" doesn't work.
  • Recycled in Space: The show's core set-up is basically a gender swapped Dexter's Laboratory from Dee Dee's point of view. The parents' basic personalities seem to be gender swapped from that show as well.
  • Red Eyes, Take Warning: The Boy-borgs and Gil.
  • Refugee From TV Land: Dawg and Bone from "Johnny Re-Animated".
  • Reverse Polarity: Averted when Johnny uses a fruit revitalization ray to bring back Porkbelly's founding fathers as zombies because the ray only works on people halfway. Susan reverses the polarity on the ray to de-animate the founding fathers but it doesn't work because they're already sort of dead.
  • Right on the Tick: Subverted, as it wasn't really the start of summer vacation.
  • Rube Goldberg Device: Dukey builds one of these to trap Johnny's Evil Twin. Subverted when the Evil Twin figures out the trap and steps over the trigger... into the actual trap which is a covered hole in the ground.
  • Salt and Pepper: Subverted with Mr. Black (The white guy) and Mr. White (The black guy), whom seem to have little difference personality-wise.
  • Sarcastic Confession: Hugh Test angrily demands to know if Johnny lost his phone, so Susan tells their dad that they're looking for Johnny's phone with baseball bats because they want to smash it before it takes over the world. Which they are.
  • Screw Yourself: In the episode "Johnny Alternative", it's strongly implied that Johnny has fallen in love with what is obviously a female version of himself.
  • Schoolgirl Rival: Sissy to Johnny
  • Self-Deprecation: "The Nightmare House! Super funny ending not included."
    • Though that seems more like "you TOO can have this nightmare house, but it won't come with the SUPER FUNNY ENDING we have here!"
  • Selective Obliviousness: Hugh Test clearly chooses to ignore the fact that nobody likes his cooking, regardless of horror struck faces, audible gagging, running to vomit and being told to his face that his cooking is aweful. The most he ever said about people opinion of his food is "I'm beginning to think you people don't like my meatloaf."
  • Sensitive Guy and Manly Man: Johnny (macho) and Dukey (sensitive).
  • Shallow Love Interest: Gil to Mary and Susan.
  • Shout-Out: One episode has Johnny turned into a mouse, and the villain is a cat. Predictability ensues.
    • One of the early episodes had a toy series called Roboticles. Coincidentally, Johnny's voice actor would later voice a character in the actual series.
    • At the end of "Johnny vs. Bling Bling 3", Johnny steals a page from John McClane's book (specifically, "surrendering" with a weapon taped behind him).
    • One one-off NPC is wearing Luigi's hat.
    • "Whatcha doooin'?"
    • The sleepover episode turns into a Cat in The Hat homage halfway through, with Bling 1 and Bling 2 running around with kites, a talking fish, and Dr. Seuss dialogue and gadget designs.
    • In Johnny of the Deep, Bling Bling loses a ring that hypnotizes Susan into falling in love with him. When it falls overboard, he says "It was the rarest of gems."
    • The episode where Bling-Bling gets his mission to destroy Johnny ends up as a Road Runner reference, complete with Canis Latinicus scientific names for the character.
    • "Johnny Dukey Doo"
    • In one episode, Johnny gets a brown, bushy mustache. When questioned about his name, what does he say it is? Earl.
    • Hi-Pitch Hal
  • Single-Minded Twins: The twins avert this but avoid being Different As Night and Day. They do not wear the same clothes and hair styles, and have different voices, but don't have exact opposite personalities. A very rare case of a cartoon making (relatively) normal identical twins.
  • Snark Knight: Jillian, Darth Vegan's daughter.
  • Snowlems: The Brain Freezer attacks Porkbelly with a whole bunch of them.
  • Space Whale Aesop: The show throws an Anvilicious video games rot your mind Aesop by having Johnny be unable to stop thinking about inanimate objects becoming random monsters. Which would be completely unimportant if his sisters didn't get a "make imagination real" helmet stuck on his head.
  • Spoiled Brat: Johnny.
  • Spot the Imposter: When the military builds a Johnny Cyborg, it invokes this trope to avoid being shot by Dukey.
  • Stalker with a Crush: Bling Bling Boy with Susan; Susan and Mary with Gil.
  • Sure, Let's Go with That: Susan and Mary use this when Hugh claims that Johnny is having an allergic reaction to the meal he made. The truth is that Johnny's brain has been devolved due to an experiment.
  • Take Over the City: Lampshaded when Mr. White & Mr. Black ask why the show's villains always seem to attack Porkbelly.
  • Take That Us: When confronted with the cartoon "Dog and Bone" which has a near-identical premise to his life, Johnny simply asks "Who'd want to watch something like that?" before glancing at the fourth wall.
  • Tempting Fate: Any time anyone says "We're safe! We're all safe now!" is a cue to the universe that it's time to make them unsafe again.
  • This Is No Time for Knitting: Johnny—confronted by some giant moon-men—hastily makes paper planes and throws them to poke the giants in the eyes, but not before Dukey scolds him for making paper planes.
  • Three... Two... One...: All the time.
  • Time Machine: Susan and Mary designed a time machine in the shape of a tea house.
  • Token Evil Teammate: Bling Bling Boy is this just as often as he is the antagonist.
  • Too Dumb to Live: Johnny, especially in Johnnyitis.
  • Totally Radical: Like you wouldn't believe.
  • Totem Pole Trench: Susan and Mary do this to get into a top secret lab. Johnny and Dukey use this to try and get past the ski captain to shred the Behemoth.
  • Trademark Favorite Food: While meatloaf certainly isn't the favorite food of most Test family members, it's obviously the favorite of Hugh's - since he's making it every night.
    • Described by Dukey as "dry as a desert muskrat."
    • Dukey will do anything for steak.
    • Dark Vegan and toast. He spends one episode trying to get home to Veganda, only to find out there's no toast there. So he immediately returns to Earth. Another episode he plans to destroy the home planet of the Rib-eye Knights because he can't keep from burning his toast. Once Johnny shows him how to do so, he immediately drops the plan and befriends the Knights.
  • Trainstopping: Practically a Running Gag whenever Johnny X is involved; one episode took it into Overly Long Gag territory that culminated in "WHAT IS WRONG WITH THE TRAINS IN THIS CITY?"
  • Twin Threesome Fantasy: Uniquely for this trope, it's the girls (Mary and Susan) who want this with Gil. They're always trying to make Gil "fall in love with us"!
    • Though they seem to vary on whether they actually want to share him or not.
  • Typo On the Cover: The title screen of the episode "Johnny Get Yer Gum" actually says "Johhny Get Yer Gum."
  • Uncanceled: Teletoon had ordered and shown new episodes after a year lull and recently Cartoon Network has been showing these new episodes.
  • Veganopia: Dark Vegan provides a Take That against this trope.
  • We Could Have Avoided All This: Dukey wonders at the end of Johnny Test: Monster Starter why the helmet can't affect itself so that Johnny can remove it. Cue Susan and Mary facepalming.
  • We Want Our Jerk Back: The subject of two different episodes. In one the change is forced on Johnny by his sisters, in another Johnny's personality is changed to more easily work with a classmate.
    • Three, if you count the episode where Dad was replaced with a robot duplicate.
  • Where The Hell Is Porkbelly?
    • Between the various hockey references (including scenes of Johnny and other kids playing street hockey, and hockey apparently being Johnny's favorite sport), and its closeness to the Canadian border in "Johnny Moustache", it's possibly in Minnesota.
      • According to the flag flying above the school in "Old School Johnny"... Ontario.
      • Most of the show was done by Teletoon, a Canadian company, so they probably got lazy and put it in Ontario. Despite things like the CIA and the Area 51 knockoff, and the White House...
      • It wouldn't be the first time Teletoon moved a series from the US to Canada when they took over it's production - see Whats With Andy.
      • One episode includes a California flag for some odd reason. So... does this mean that the show is back in the US, or is Canada screwing with us?
  • Who Would Want to Watch Us?: "Dawg & Bone" is an in-universe cartoon about a boy who has genius twin siblings and his dog and the adventures they have together. Johnny and Dukey consider the show lame.
  • Wild Card Excuse: Dukey the speaking dog is always "a kid with a rare hair disorder".
  • World of Ham
  • A Worldwide Punomenon: The Bee Keeper's and Brain Freezer's puns related to bees ("Bee afraid! Bee very afraid!") and cold ("Time to chill out!"), respectively. The latter is most likely a reference to Mr. Freeze from Batman and Robin.
  • Yandere: In one episode, Johnny asks his sisters for super-intelligence. He obtains a pair of pants, which become self-aware...and this.
    • The girls create three robot boys to make Gil jealous. It works. In both directions.
