Bart manipulates Homer's and Marge's different ways of disciplining him ó and ends up nearly driving them to divorce.

!! Tropes:

* AttentionDeficitOohShiny: Homer checks out of the empty womenís restroom at the subway for a moment to find a sofaÖ after getting a nickel.
* BaitAndSwitch: What seems to be a thought baloon with Nelson is actually Nelson burning some books.
* BookEnds: The episode starts with "Springfield of Tomorrow" and ends with more of that story being shown.
* ChekhovsGun: The long-abandoned subway is mentioned in the "Springfield of Tomorrow" film.
* ComicallyMissingThePoint: After squeezing his way in an abandoned subway station, Homer finds a nickel and squeezes himself out. He then pays the fare and enters again.
* GettingCrapPastTheRadar: At the end of the "Springfield of Tomorrow" film, it's stated couples can freeze their kids for when they need privacy.
* HandsOffParenting: When Homer and Marge grew tired of Bart manipulating them, they opted for this until they learned of his plan to destroy Springfield with the abandoned subway.
* HarmlessFreezing: Happens to a boy in "Springfield of Tomorrow" when his parents want privacy.
* IdeaBulb: Itchy breaks one and stabs Scratchy with it.
* NoodleIncident: Bart was able to cheat on a rectal thermometer. If he doesnít want to talk about it, then one rather not asks.
* OutOfCharacter: Homer is unusually strict in this episode towards Bart. He almost sadistically wants Bart to do more homework than is required of him, and refuses to let him take even a short break despite him actually doing it.
* KidHasAPoint: Nelson explains to Bart why he isnít getting his fix and Lisa at the end.
* SomethingOnlyTheyWouldSay: Lisa figures out it was Bart who wrote the letter their parents think she wrote because only Bart would misspell "Elementary".
* ShoutOut:
** While Bart does his big load of homework, he watches a parody of ''Anime/{{Pokemon}}'' on TV and comments [[LongRunner how it hasn't run out of]] [[SeasonalRot ideas yet]], [[{{Irony}} which is ironic]]. This is a nod to ''[[VideoGame/PokemonGoldAndSilver HeartGold and SoulSilver]]'', which was released in the United States on the same day of the episode's airing.
** The Itchy and Scratchy cartoon featured in this episode is a parody of ''Series/{{House}}''.
* TookALevelInJerkass: Bartís plan on destroying the school with the abandoned subway.
** Homer wanting Bart to do more work than he is supposed to.
* {{Zeerust}}: "Springfield of Tomorrow" (Copyright MCMLVI) is chock-full of it.
