In this, the 500th episode, the town of Springfield has had enough of The Simpsons and banish them to live off the grid.

!! Tropes:
* ComicallyMissingThePoint: This entire dialogue
-->'''Brockman:''' All Springfielders should now move off the streets and inside their homes. Please avoid the superstitious panic that marked the recent lunar eclipse.
[a picture of Homer rioting, standing on Abraham Simpson is shown]
-->'''Homer:''' Heheh. Sorry dad. I was afraid the dragon wouldn't cough the moon back up.
-->'''Grampa:''' You idgit! The dragon always coughs the moon back up.
-->''Lisa:''' I know it's futile but I must again point out, there is no dragon.
-->'''Homer:''' Then why am I paying $800 a year in dragon insurance?
-->'''Lisa:''' Again, I maintain that money would be better spent on car insurance.
-->'''Homer:''' Lisa, everyone knows that dragons do not attack cars. Geez, pick up a book.
-->'''Lisa:''' [annoyed] I pick up books like you pick up beers!
-->'''Homer:''' Then you have a serious reading problem.
* ContinuityNod: Bart's [[Recap/TheSimpsonsS11E2BrothersLittleHelper prank]], Homer's [[Recap/TheSimpsonsS10E11WildBartsCantBeBroken drunken rampage]], and Lisa's [[Recap/TheSimpsonsS21E19TheSquirtAndTheWhale activism]]
* 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.
* EnfantTerrible: The people of Springfield accuse Maggie of being this.
* 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.
* TheyWastedAPerfectlyGoodPlot: A 500th episode milestone could've had a nicer episode, but what we have here is the entire town of Springfield giving the Simpsons a hard time once again.[[note]]In fact, the only good milestone episode was the 100th, where Skinner gets fired and Bart befriends him. The 200th, while funny, was the harbinger of JerkAss Homer. The 300th where Marge becomes a bodybuilder was criticized for Marge's change in body and personality. The 400th, where Kent Brockman gets in trouble for swearing on live TV, was too middle-of-the-road to be truly memorable -- outside of the special opening which featured the Tracy Ullman ''Simpsons'' short, "Family Portrait" and most people hated it because of the FOX News/conservative/Republican bashing[[/note]]
** DoesThisRemindYouOfAnything: ...though the plot of everyone in town becoming sick of ''The Simpsons'' and banishing them, only to realize they do need them in their lives does make a good premise for a 500th episode, as it shows that as much as viewers (the people of Springfield) hate The Simpsons because of their current, mediocre-to-unwatchably bad episodes (current, destructive antics that have nearly bankrupt the town), they can't fathom what Sunday nights or the FOX network would be without it, so they choose to welcome them back. In short, the entire episode is an allegory of how viewers feel about the show (they hate that it has gone to pot, but most watch it anyway because there is some good in it and can't really fathom what life would be like if it was never there).
* WithFriendsLikeThese: The Simpson family are spared by no one. This includes their so-called close friends, even other family members. Only Flanders tries to talk in their favor, and is silenced with a battering ram.
* DisproportionateRetribution: One of the reasons that the Simpsons are hated is because Maggie (a baby) doesn't talk.
* KarmaHoudini: The entire town doesn't even apologize for banishing the Simpson family, even after moving to the outlands with them.
