In this, the 500th episode, the town of Springfield has had enough of The Simpsons and banish them to live off the grid.
!! Tropes (YMMV tropes can be found [[YMMV/TheSimpsonsS23E14AtLongLastLeave here]]):
* 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 pranks]], Homer's [[Recap/TheSimpsonsS10E11WildBartsCantBeBroken drunken rampage]] (which was blamed on the kids in town in that episode, but there was no scene where the police realize that it was caused by Homer and his drunken friends until now), and Lisa's [[Recap/TheSimpsonsS21E19TheSquirtAndTheWhale activism]].
** Homer mentioned when he first moved to the house he "Used to talk like this" referencing the Walter Matthau voice he used in the early seasons and "The Tracy Ullman Show".
* 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.
* DisproportionateRetribution: One of the reasons that the Simpsons are hated is because Maggie (a baby) doesn't talk.
** They also find Lisa's acts of activism very irritating.
* DoesThisRemindYouOfAnything: 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 their latest episodes (current, destructive antics that have nearly bankrupt the town) aren't as good, 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).
* EnfantTerrible: The people of Springfield accuse Maggie of being this.
* GenreSavvy: Mayor Quimby knew that Ned Flanders would talk the entire town from exiling The Simpson Family so he activated a battering ram to prevent it from happening.
* JerkassRealization: The townsfolk when Homer and Marge go back to the outlands as the people there accepted them for who they are. And after being called jerks by Homer.
* KarmaHoudini: The entire town doesn't even apologize for banishing the Simpson family, even after moving to the outlands with them.
** Subverted with the Simpsons family itself after the town are finally tired of putting up with them.
* NegativeContinuity: By the end of this episode, every Springfielder moved to the Outlands and nobody expressed any intention to return. In the next episode, things are like this one never happened.
* NeverMyFault: Marge lashing out at Springfield for not letting them be themselves. Despite being shown earlier that being themselves causes the town no end to problems.
* NobodysThatDumb: Homer and Marge sneak back into Springfield under the disguise of Mr. Burns and Smithers. When Chief Wiggums first spots them, it appears that he fell for it but it's later revealed that he had seen through their disguises and only pretended to be fooled in order to have time to rally the people to arrest Homer and Marge.
-->'''Chief Wiggum''': You really thought you could fool me with that Burns and Smithers getup. I mean, I'm not the sharpest pencil in the pencil thing, but I'm least as smart as a cat. Right, Lou?\\
'''Lou''': Uh, what breed, Chief? I mean, I saw an Abyssinian once who could change channels.\\
'''Chief Wiggum''': Eh, that is pretty smart.
* 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.
* WhateverHappenedToTheMouse: Grandpa Simpson disappears from the story after The Simpsons Family was exiled from Springfield and the parade that followed it.
* WithFriendsLikeThese: The Simpson family are spared by ''no one''. This includes their so-called close friends and other family members. Only Flanders tries to talk in their favor, and is silenced with a battering ram.
