Fantasy Planet - S2.E24

With all the problems the Jetson family have, they decide to take a trip to Fantasy Planet. The host—named Mr. Rocket (played by Sonny Melendrez and a take on "Mr. Roarke" from Fantasy Island)—has each family member in capsules to live out their fantasies:

George: Boss of Jetson's Sprockets

Jane: Queen of an asteroid where she does absolutely nothing

Judy: World-renowned pop star

Elroy and Astro: Superhero team

After realizing their fantasies aren't really what they were looking for, they use a special "stop watch" that can end their fantasies.
