In this, the 500th episode, the town of Springfield has had enough of The Simpsons and banish them to live off the grid.
* CouchGag: A collection of the couch gags from the previous episodes, culminating into a mosaic reading "500," which falls apart, revealing Homer and Bart strangling each other in tuxedos.
* RetroactiveWish: When the Simpsons were banished from Springfield, Homer announced he'd curse the town into a hundred-year drought and it started raining soon after. Homer then tried to change it to a hundred-year rain and then the rain stopped and a rainbow showed up. Homer weakly tried a "good weather" curse.
