The Fairly OddParents

The Fairly OddParents is an American animated fantasy television series created by Butch Hartman for Nickelodeon. The series began life as a segment of Oh Yeah Cartoons! in 1998 before being turned into a full-fledged series in 2001. It lasted until 2017, spanning 172 episodes across 10 seasons. During the series' run, there were also several television movies (three of which were live-action). A live-action sequel series Fairly OddParents: Fairly Odder began airing on Paramount+ in 2022.

Timmy Turner is given two magical fairies; Cosmo and Wanda, after being neglected by his parents and bullied by his babysitter, Vicky. Cosmo and Wanda's job is to grant Timmy any wish as long as it doesn't go against Da Rules. Having run out of ideas in 2008, the series jumped the shark and saved itself from cancellation by introducing Cosmo and Wanda's baby, Poof, which was then followed by Timmy's magic dog, Sparky, and Timmy's neighbor, Chloe Carmicle, with whom Timmy has to share Cosmo and Wanda.

Since Hartman previously worked at Hanna-Barbera, it's no surprise he would squeeze in references to his old job's cartoons.

Flintstones

 * Channel Chasers (part 2): Timmy, Cosmo, and Wanda are sent into a parody of The Flintstones called The Meatflints. They live life like a "modern stone-age family" as Timmy puts it, and proceed to work the TV remote in typical Flintstones fashion with a tiny pterodactyl flying out to turn on the TV. Meanwhile, Cosmo disturbs a sleeping sabretooth tiger resembling Baby Puss with Dino's color scheme. They run around the house in a background loop mocking the limited budget that Hanna-Barbera had, with the pterodactyl commenting, "It's a cycle," instead of the usual "It's a living." (He also appears later in the Scooby-Doo parody where he comments on the chase scene.) They then hop into the Flintmobile, and while "driving away," Timmy points out that if the cars in this show are powered by feet, shouldn't they just keep running? During this time, Timmy, Cosmo, and Wanda are dressed like Bamm-Bamm, Fred, and Betty respectively, while still retaining the colors of their own outfits. There is also an error as the Meatflints on the TV Guide is called The Turnstones.

Jetsons

 * Channel Chasers (part 1): Timmy zaps himself into the world of The Futurellis, which is about a futuristic Italian-American family who are a parody of the Jetsons family as well as the mafia family Sopranos from HBO's The Sopranos. Timmy's entrance is similar to both the opening and closing theme songs, with Timmy (dressed like Elroy) driving a flying car shaped like a saucer just like George does in the opening. All the characters are supposed to be robots, although Timmy is unaffected by this fact. Along the way, he meets Tony Futurelli taking his dog for a walk on a treadmill shaped like a pizza, just as George took Astro for a walk on a treadmill in the closing credits. Tony mocks Timmy's ride, and then his dog sees a cat just like Astro saw a cat, but Tony's dog has beef with the cat because he owes the dog money. The dog chases the cat which causes Tony to fall and get dragged. Tony then shouts, "Maria! Get me off this crazy thing!" The dog and cat then jump on the balcony to watch Tony continue to spin around.

Jonny Quest

 * Channel Chasers: In part 1, Timmy zaps himself into a parody of Jonny Quest called Jonny Hunt. Jonny and his family are riding a riverboat in the jungle trying to escape a giant scorpion-looking robot. Timmy, who is dressed like Jonny Quest, saves them from certain doom by using his magic TV remote to get rid of it. The team thanks him and invites him on dangerous missions in which he'll get to use deathly weapons. As a parting gift, Timmy takes back a bazooka, which blows up half his house by accident as Jonny Hunt plays on his TV. In part 3, Timmy uses a Jonny Hunt lunchbox as a time capsule, which his kids dig up 20 years later.

Josie and the Pussycats

 * "Shelf Life:" Tom Swayer changes the story Jason and the Argonauts so that Jason and his Argonaut soldiers are magically changed into a music band "Jason and the Pussycats," singing a parody of the theme song to fight off a cyclops.

Scooby-Doo

 * "Twistory:" The Founding Fathers are all astonished to discover that Benedict Arnold was disguising himself as George Washington, which is uncovered by Timmy, eliciting Benedict's angry remark, "And I would have gotten away with it, too, if it weren't for that meddling kid."
 * Channel Chasers (part 2): Timmy, Cosmo, and Wanda travel into a parody of Scooby-Doo, Where Are You! called Snooper Dawg and the Clue Crew. The Clue Crew arrive in their Clue Cruiser right after Timmy and the fairies enter, with the fairies going from parodies of Mystery Incorporated like Timmy, to parodies of Scooby. There are several tropes and conventions followed, such as Snooper the dog's Shaggy-like friend jumping into his arms after they all spot a monster, and run into the nearby spooky mansion which has bats flying out of it. Inside, they participate in the Scooby-Dooby-doors (with an accompanying pop song), Snooper and his friend eat, and the Velma doppelganger loses her glasses. They catch the monster and unmask it. There seem to be references to Goober and the Ghost Chasers, too, as the dog is somewhat similar to Goober and the kids are made of five, instead of four.
 * "Dread N Breakfast:" During Crocker, Tootie, and Dark Laser stay at the Turner Bed and Breakfast, they are out to get Timmy, who at one point asks Dark Laser what one of his buttons does which he says turns on his 70s chase music, which begins a Scooby-Dooby-doors chase. In the middle of the chase, parodies of Shaggy and Scooby appear, being chased by the Headless Horseman; the Shaggy parody says "Zinkies, Doob! Like, keep running man!"
 * "The Wand That Got Away:" While on the search for Cosmo's wand, the gang gets into Spark's "groovy" van (resembling the Mystery Machine) he won from a 1970s game show. This gives Cosmo the idea, with Wanda's wand, to turn them into Mystery Inc. When they track it down to Crocker's house, they split up and run into monsters (and Crocker's mother). Crocker thinks the wand is fake when he wishes to be a zillionaire, causing an oil spill outside, which he doesn't see as helpful, but when he realizes it was real he says to himself, "And I would've gotten away with it, too, if it weren't for those meddling kids." When the gang is back at Timmy's, Wanda is relieved they won't have to solve any more mysteries, which is followed by Sparky crying, "Rooby-Rooby-Roo!" But Sparky insists he says this right before seeing a giant pigeon smack into a window, such as the one Mr. Turner transformed into is about to do. Mr. Turner reacts by saying, "Zoinks! I broke my jinkies!"

Space Ghost

 * Channel Chasers (part 2): Timmy, Cosmo, and Wanda are sent into a parody of Space Ghost called Space Spectre. Space Spectre is nowhere to be seen, aside from his face being used as a logo on the Phantom Cruiser-type spaceship and Timmy, Wanda, and Cosmo's uniforms. Timmy, Wanda, and Cosmo are parodies of Space Ghost's sidekicks, Jace, Jan, and Blip, respectively.

Tom and Jerry

 * Channel Chasers (part 2): Timmy, Cosmo, Wanda, and Future Timmy travel into a parody of Tom and Jerry called Ted & Jimmy, with Timmy and the fairies in the role of Jerry and Vicky in the role of Tom. There's even a dog like Spike. Cosmo and Wanda jump in front of the screen every time there is violence and comment they can't believe how this wasn't censored in the 1940s.
 * "Mouse Capades:" Timmy, Cosmo, and Poof tuned in to see Sleazy and Cheezy!, When it's over, the impressionable baby Poof sees the animosity between Vicky and Timmy as a means of continuing watching Sleazy and Cheezy!, so he transforms them into his very own Sleazy and Cheezy/Tom and Jerry.

Yogi Bear

 * The Timmy and Jimmy Power Hour: When Jimmy Neutron tries to explain to Timmy's classmate that he's not Timmy, Sanjay mocks him by saying "I'm not Sanjay, I'm Yogi Bear and I am smarter than the average bear."
