Recycled in Space/Western Animation

In the Aqua Teen Hunger Force episode "100", the theme from the in-story "reimagining" ends with the words 'in space'.
Silverhawks is Thundercats IN SPACE! (Compare Mumm-ra's and Mon-starr's Transformation Sequences.) It even used most of the same voice actors. Rather odd in that Thundercats is in space in the first place...
On a related note, Tigersharks (part of a short-lived programming block called The Comic Strip) is Silverhawks... UNDER WATER! Who lives like the Thundercats under the sea? The... Ti... Ger... Sharks!
The Flintstones is The Honeymooners AS CARTOON CAVEMEN!
The Jetsons is The Flintstones IN THE FUTURE! (A crossover cartoon, titled The Jetsons Meet the Flintstones, pretty much cements this notion.)
- IN SPACE!
South Park played it completely straight. There was an episode Starvin' Marvin, followed two seasons later with Starvin' Marvin IN SPACE.
Star Wars: The Clone Wars seems to love it, especially during the second season:
- "Senate Spy" episode was Notorious IN SPACE, according to the writers.
- "Landing at Point Rain" was (again, according to the producers) the first act of Saving Private Ryan IN SPACE.
- "Legacy of Terror" and "Brain Invaders" are Zombie Apocalypse IN SPACE.
- "Bounty Hunters" is Akira Kurosawa's The Hidden Fortress IN SPACE, indicated by the memory card at the beginning.
  - George Lucas was heavily influenced by Kurosawa. Guess which Kurosawa film's influence stands out most in the original Star Wars movie.
- "Zillo Beast" is Godzilla IN SPACE, while "The Zillo Beast Strikes Back" is more like King Kong IN SPACE.
- Cad Bane was designed to be Lee Van Cleef IN SPACE.

The Roman Holidays is Make Room For Daddy IN ANCIENT ROME!
There is an Animated Adaptations of The Partridge Family set IN THE FUTURE! (It was originally to be The Jetsons a few years farther into the future.)

- It was followed by Gadget Boy and Heather, which was Inspector Gadget AS A SIX-YEAR-OLD! With Penny AS AN ADULT! And Brain AS A ROBOT! And Chief Quimby AS AN ITALIAN!

There was an IN SPACE! Animated Adaptation of Gilligans Island, titled Gilligan's Planet.
The original animated version of The Addams Family was ON THE ROAD IN A HOUSE-SHAPED CAR! The 90's version was essentially just an Animated Adaptation of the movies, though.

Duck Dodgers is DAFFY DUCK IN THE 24TH-AND-A-HALF CENTURY!

Aversion. The Futurama writing staff have claimed that a large part of the reason behind the Executive Meddling that the show suffered was that, much to the network's annoyance, the show was not The Simpsons IN SPACE!
- Directly referenced in "Into the Wild Green Yonder":

Bender: It's gonna be fun on a bun! IN SPACE!

- A canon example, however, is that apparently the only reason Fry accepted another delivery boy job (after having basically losing the one from his own time and running away from the one being assigned to him forcibly) was that it was IN SPACE!
- Some fans have affectionately described Futurama as Friends... ANIMATED AND IN SPACE!

- Pound Puppies (especially the 2010 revival, which is made by the creators of Recess) is Hogan's Heroes IN A DOG POUND!

Danny Phantom is Spider-Man WITH GHOSTS! It even has Expies to Spider-Man characters.
Ben 10 is Dial H for Hero WITH A GUI INSTEAD OF AN RNG, AND WITH ALIENS!
The Life and Times of Juniper Lee is pretty much American Dragon: Jake Long, JUST FEMALE!

Batman OF THE FUTURE was an actual title used for Batman Beyond in certain markets.
- Showdown, an episode of Batman the Animated Series featuring a Jonah Hex storyline, was made because the writers recognized Hex as Batman OF THE OLD WEST!
Tom and Jerry relies on this trope a lot. Granted, it's because there's only so much you can do when the premise of the entire series is "cat chases mouse."
Popeye received similar recyclings, especially once Famous Studios took over in the 1950's and the writers ran out of ideas.
Zorro: Generation Z is Zorro IN THE FUTURE! How far is unknown, because it looks a lot like the present with added Family-Friendly Firearms.

When the final season of Hanna-Barbera's All-New Popeye Hour during the late 1970's was reformatted into The Popeye and Olive Comedy Show for its final season, one of the segments was called "Prehistoric Popeye." Basically a combination of Popeye and The Flintstones with Popeye eating his spinach out of cans made from rocks!!
Several Veggie Tales videos often do this to several stories from The Bible, such as the story of Joseph and the Exodus IN THE OLD WEST, and the story of Shadrach, Meshach, and Adbenago AS FACTORY WORKERS!
