Kafka Komedy: Timmy's life is so horrible that he must have fairy godparents to compensate for it. Even then, a poorly thought-out wish can make his problems worse.
And sometimes, even a well thought out wish can backfire, as shown in the episode Just The Two of Us, showing that Timmy is indeed a Cosmic Plaything and Butt Monkey.
Karma Meter: In "Power Mad," where Timmy wishes up a challenging virtual reality game in which you can die if you lose your three lives and Chester and A.J. get stuck in it, Timmy sacrifices his own last life to save theirs. The game rewards him for his Heroic Sacrifice with enough points for a 1Up.
Kid Hero: Timmy Turner. While he usually fits the trope Designated Hero, there have been situations where events have been beyond his control. When this happens, he WILL step up to the plate and become a genuine hero. Wishology is the best known example of this.
Low Speed Chase: Timmy is trying to outrun his mind-controlled friends, who are trying to capture and brainwash him. However, their scooters are set to a mere 2 mph — any faster would mean they would spill their milk (the source of the mind control).
Mike Nelson, Destroyer of Worlds: While being put through Fairy Academy, Cosmo ended up destroying Pompei, turned Xanadu into Pittsburg, and sank Atlantis... NINE TIMES.
In another episode, the evil bug that crawled up Vicky's butt inhabited the President of the country and made him bring out a button that could destroy the planet. At the end of the episode, Cosmo pushes it and destroys Pluto.
"He said THE planet. He didn't say which one."
Actually, the President just happened to have the button with himself. The bug never made it to...er, the President's butt.
In one episode early on in the series, Cosmo was required to do one sufficiently evil act within a 24 hour period or his fairy license would be revoked and he'd be sent back to training. After consulting Vicky for advice, she suggests he blow up the Earth, and he would have done it, if not for the fact that he reverted back to his normal self at 12:00:00 Midnight, and the Earth would have otherwise blown up at 12:00:01 AM.
In the same episode, Wanda says that for her evil act she wiped out the dinosaurs.
Blowing up planets seems to be a standard affair for the Yugopotamians.
"We wouldn't have to blow up all these planets if you just stopped and asked for directions!"
Missing Episode: Hail to the Chief and Twistory for being offensive. It portrays the Founding Fathers as kinda wacky characters, especially George Washington, who's an Ax CrazyBad Ass with An Axe to Grind (a borderline textbook example of a Memetic Badass).
The episode is still shown in other countries.
It is also available over Netflix in America as a part of Season 1.
The Movie: Holds the record at Nick for the most made-for-TV movies with a total of 10 films so far. (12 if you count the Wishology movies as separate films)
Wishology is especially notable given Nick's standards of what a "movie" is. Atlantis Squarepantis was called a movie. It was 30 minutes long. Wishology is two hours twenty four minutes, and is the only episode of FOP (besides the live-action movie) broadcast in widescreen high definition.
Mundane Made Awesome: Twistory. Aside from the episode itself (alongside Hail To The Chief, tied to it) being a glorified educational episode, it doesn't just involve Timmy doing his essay by directly asking the Founding Fathers themselves, but for doing so, Timmy hosts a self-titled talk-show, the "Timmy Turner Show". Filmed in Timmy's treehouse. Timmy himself just seems to be screaming to the audience, like, "hey look, it's educational yet entertaining". However, when his wish (as usual) backfires, since the Founding Fathers' absence from their age turns the States back to the British colony they once were, well... I think you know what happens.
Mundane Wish: Crocker teams up with Norm the genie but instead of simply wishing Timmy to Mars (as Norm suggests) or simply wishing to have a fairy in his possession he wastes his wishes on parts for ridiculous traps that backfire on him. Norm allows Crocker to wish for more wishes — which he does by wishing for them three at a time — and continues to waste them.
While many of Timmy's wishes seem wasteful, they don't qualify because he has unlimited wishes. In fact, it's actually bad for the fairies if he doesn't constantly wish for things
Timmy's was lampshaded when comic book people believed he was the infamous super hero 'Naked Lad'. (Bonus points for the comic book cover; it's Timmy's head with a musclar body!)
Negative Continuity: Especially in light of the Wishology special. This special had featured a considerable amount of Character Development for many of the minor characters. In particular, the main character, Timmy, finally was Genre Savvy. Subsequent seasons show NONE of these developments.
Nerds Are Sexy: Winston Dunnsworth, who appeared in the episode "A Bad Case Of Diary-Uh!", has this appeal In-Universe.
Nice Job Breaking It, Hero: Timmy frequently, especially when it came to Crocker's fairy obsession (actually that was Cosmo's fault.)
No Indoor Voice: Mr. Turnbaum has a bad habit of ANNOUNCING THAT EVERYTHING THAT HE AND HIS WIFE ARE COMMITTING IS BY THEM, THE REAL TURNBAUMS! Mrs. Turnbaum doesn't like it when he does that.
As well as Mr. Crocker whenever FAIRY GODPARENTS come up. Also when he is working out a secret plan... even when Timmy or someone else is right there.
Timmy: Hello, I'm right here. I heard everything you just said.
Mr. Crocker: Good. Then I won't have to repeat everything I just said.
No Sympathy: In the episode Bad Heir Day, Timmy, who has risked his life trying to find his godbrother, Poof, is given no sympathy by Wanda despite it being clear he's a Badly Battered Babysitter, mostly because he lied to Wanda about Poof's whereabouts.
Timmy: (holds up a net) Mom, don't ask why, but I have to stick this in Dad's pants.
Mom: Oh, is it Fathers Day already?
We never do find out exactly why Mr. Crocker was banned from entering Cincinatti, although one can safely assume it probably had to do with proving the existence of FAIRY GODPARENTS!!!
Not Allowed to Grow Up: All the kids. In fact, there have been various episodes depicting the last day of school (all of which pay no mind to continuity) yet they all stay in the same class, in the same grade, with the SAME teacher!
In addition to the multiple summers, one movie explicitly takes place one year after he got his fairies, which is retconned to have happened a year earlier.
Averted by the live action movie, which will show the future of most of Timmy's human friends and enemies.
Referenced yet AGAIN in Timmy's Secret Wish, where we discover that apparently Timmy wished that everyone on Earth, including himself would never age so he could keep Cosmo and Wanda forever...which he did 50 YEARS AGO.
Only Child Syndrome: It's easier to list the aversions: Tootie and Vicky, Cosmo and Schnozmo, and Wanda and Blonda. Almost every character in the series lacks siblings.
Or So I Heard: Big Wanda When Wanda takes over her father's business, she put a ficus in the meeting room. One of the men comments on a gardening tip for it, then quickly invokes this trope when the others stare at him surprised.
"A ficus? That's gonna need more light... not that, I would know."
The Other Darrin: Robert Cait replacing Norm Mac Donald as the voice of Norm the Genie, Butch Hartman replacing Gilbert Gottfried as Dr. Bender, and Jason Marsden replacing Frankie Muniz as Chester, to name a few.
The Other Marty: Tara Strong redubbed the Oh Yeah! Cartoons shorts after she took the role of Timmy. Timmy was originally voiced by Mary Kay Bergman, but was replaced following Bergman's suicide.
Papa Wolf: Often averted for both Cosmo and Timmy's Dad. Whenever their respective sons are threatened they try to be heroic... with mixed results.
Paper-Thin Disguise: Several. For example, Timmy's "Cleft the Boy Chin Wonder" superhero costume. Even though having a red costume with yellow cape, boots and gloves, as well as black briefs and a black mask, the buckteeth and the red variant of Timmy's typical pink baseball cap give it all off. And we thought costumes were effective in keeping vigilantes' true identities hidden...
Parental Neglect: Timmy's parents are quite neglectful and extremely selfish. They do love him though; they're more like adult children than truly evil abusers. Still, there are times when they put Timmy's happiness after their own, and in the "Wishology" trilogy they fail to notice he's been in Fairy World for an extended period of time, and don't notice they forgot to take him on two family vacations. It speaks volumes when, in part one, Timmy shrugs off the fact that they don't remember they have a son. The mother has even openly spent Timmy's college fund on stuff for herself when viewing the home shopping channel
Played for Laughs when his parents are busy watching tv about a show called the Bad Parent Hunter. So that Timmy won't disturb them, they hand him a bottle of acid and tells him to go play in the street - which he does
Guess who Crickey the Bad Parent Hunter was hunting?
Pass the Popcorn: The Pixies in School's Out: The Musical about their evil plan and Timmy's misery.
Paused Interrupt: Despite not being a video game, this is a recurring problem with the voice acting. Any time a character is going to be interrupted, they stop short as if they can see it coming.
Picked Last: Timmy Turner was picked last for everything in Dimmsdale to the point where he got Cosmo and Wanda to make him the most wanted kid in the world. (And by wanted....let's just say that both FBI and CIA wanted him).
Plumbers Crack: In "That Old Black Magic", Timmy's Dad was so afraid of the bad luck associated to stepping on cracks on the floor he dedicated himself to sealing all cracks at the amusement park he took his family to. That included the crack of a repairman working at the park.
Pluto Is Expendable: They blew it up in Vicky loses her Icky (the bomb was supposed to blow up a planet; it never said which one)
Pokémon Speak: Poof, but he can say other things, including Timmy's name.
Da Rules probably averts this, (we haven't even seen the whole book) but what about the Magic Muffin? You can take bites out of it and as long as you don't eat the whole thing you can still nibble it for more wishes!
Precocious Crush: The episode where Timmy wishes up the 18-year old Tommy Turner, whom the 10-year old Tootie falls in love with. And the fact that Tootie is genuinely in love with him is a major plot point of the episode.
Pro Wrestling Episode: A partial example in "Odd Jobs" where Timmy's dad faces of against Crusher McPersoncrusher.
Properly Paranoid: Subverted in "Operation Dinkelberg". Knowing that Timmy's Dad thinks he's an evil villain who's responsible for all of his problems, Dinkleberg pretends to be just such a villain - For no other reason than to give Dad the pleasure of thinking he was right.
Prophetic Name: Mr. and Mrs. Turner were nicknamed Mom and Dad as children
Reality Warper: In "Mr Right!", Timmy gains the ability to make things be true just by saying they are true.
Real Men Wear Pink: Timmy is just the start. See 'What Could Have Been' for the details.
This is lampshaded in an episode. When Timmy goes back to the past, he sees his parents moving into what would be his house. In the moving trunk are pink things because his parents thought they were having a girl. What's sitting on top is his infamous pink hat.
Refugee From TV Land: The Crimson Chin taken out of his comic. This results in him discovering he is imaginary he grows giving him depression resulting in his series almost getting canceled.
Reset Button: Wishing things back to normal, along with once having a literal reset button in the form of a watch.
Retcon: A comic story revealed this in regards to the Crimson Chin's origin
Retconjuration: Some of Timmy's wishes have permanently altered the world he lives in. For example, the mountainous snow-capped central American country of Tibecuidor has always existed.
This came to a head when Timmy wished he was always right; instead of being magically prevented from saying something wrong, reality itself would be bent and altered to satisfy whatever Timmy said. Some of the changes took place immediately after Timmy mentioned them and were noticed by others (AJ wanted to study Timmy after he said there were only 49 states and the Dakotas merged into one state immediately thereafter), but some ("No I don't! I don't have fairy godparents...!") seemed to silently rewrite others' perceptions (Mr. Crocker suddenly becoming placid and saying "oh, okay then" after Timmy makes the previously-quoted claim).
Ret Gone: Happens to Poof in Wishy Wash, for unconventional reasons, the person that remembers Poof is Timmy
Rogues Gallery: Mr. Crocker, Vicky, Doctor Bender, Francis, the Nega Chin, Imaginary Gary, Norm the Genie, the Pixies, Anti-Cosmo and Anti-Wanda, Cosmo's mother, Dark Laser, etc.
Rule of Three: At least one joke is repeated thrice over the course of each and every episode
Lampshaded at one point when one character remarks that they can only use a gag three times. Makes you wonder if the writers are keeping an eye on this page.
