When the final season of Hanna-Barbera's All-New Popeye Hour during the late 1970s 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!!
Towards the end of its second season The Care Bear Family had two spin off settings using the same characters; one, aboard a starship that's a dead ringer for the U.S.S. Enterprise only made with hearts tars and rainbows, and a second set in dinosaur time.
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 notThe SimpsonsIN 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!
Don't forget that one episode with the TitanicIN SPACE! Followed in the Rebirth season with the Land Titanic! ON LAND! (and yes, both of them sinked)
A very large portion of the show's gags are simply applying this trope to any and every aspect of pop culture. Like that one joke or that one thing that everybody keeps talking about... but IN SPACE! Or at least IN THE FUTURE!
There is an Animated Adaptation of The Partridge Family called The Partridge Family 2200 A.D.. As you might imagine, this is The Partridge Family set IN THE FUTURE! (It was originally to be The Jetsons a few years farther into the future.)
When it was reformatted for syndication on the umbrella show Fred Flintstone and Friends, it was rebilled as The Partridge Family In Outer Space.
Recess is essentially Hogan's Heroes on a 1990s elementary school playground. One such episode of Recess does a very good adaptation of the Hogan's Heroes pilot and another features a scene where expies of the characters are in a Hogan's Heroes-style WWII POW camp; complete with the Colonel Klink expy wearing a monocle.
The Super Mario Bros. Super Show is practically nothing but this. Just about every episode is a different-themed world; these include IN SPACE, IN ARTHURIAN TIMES, IN JACK AND THE BEANSTALK, IN GODZILLA-TERRORIZED TOKYO, AMONG PIRATES, IN SOME MEXICAN DESERT PROTECTED BY A MASKED HERO NAMED "ZERO", IN A RACE, etc.
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 Abednego AS FACTORY WORKERS!, and the parable of the Good Samaritan AS A DR. SEUSS BOOK!
