The Simpsons 500th episode is “The most meaningless milestone of all,” warns the show’s opening theme, which combines 23 seasons of couch gags to form the number 500.
In “At Long Last Leave,” the Simpsons are banished from Springfield for causing too many shenanigans. You can almost hear Comic Book Guy yelling, “Simpsons did it!” (see: The Simpsons Movie) The exiled family moves off the grid to the Outlands, which has its own theme.
WORST… 500th episode ever!
The self-deprecating episode ends with plea for mercy: “Thanks for 500 Shows. All we ask is that you go out and get some fresh air before logging on the internet and saying how much this sucked.”
