This is an episode of The Simpsons. There will be spoilers ahead:
This episode features the Simpsons going to the planet of Kang and Kodos as captives. They get there through an elaborate and extended jape at Disney, which the show has been known to do on occasion. The Simpsons go to an amusement park, one only thinly disguised as Disneyland, with plenty of jokes at Disney's expense, all of which are gratuitously hilarious. I particularly like the first ride, which Maggie gets to pick, the sanitized Pirates of the Caribbean ride, which takes all the fun out of things and the references to Star Wars being their property now.
The Simpsons mistake a spacecraft for a ride at the park and wind up being taken for a ride. A certain squirrel and two moon men make a cameo which is not for the squeamish. I almost fell out of my chair.
The Simpsons wind up a zoo exhibit and Homer winds up on the menu, escapes with help from rebels against the ruling class on the planet and then returns in time to try to rescue his family. It turns out that the Simpsons are essentially poisonous to the aliens because of their diet (even Lisa, who is humbled a bit by certain observations). The Simpsons head out for home, with Maggie as pilot.
The end credits feature Simpsons takes on characters and scenes from Star Trek. All in all, a very good episode. Recommended.
