First Aired - 10/27/1996

This year's tales of terror include Bart meeting his long-lost Siamese twin who lives in the attic and has gone insane, Lisa becoming a goddess to a small civilization she created out of a tooth, some cola, and Bart zapping her with static electricity, and Homer trying to stop Kang and Kodos from posing as Bill Clinton and Bob Dole and running for U.S. President.

* AnalProbing: Homer assumes Kang and Kodos want to do this, and starts to take his pants off before they make it clear they ''really'' don't.
* {{Anticlimax}}: The ending of "The Genesis Tub"
* [[spoiler: TheBadGuyWins: "Citizen Kang"]]
* BerthaInTheAttic: "The Thing And I"
* TheCassandra: Kang and Kodos sprayed Homer with booze to make sure nobody would believe him. Probably nobody would have believed him anyway given that he was [[YouHaveToBelieveMe ranting about an alien invasion]].
* ComicallyMissingThePoint: [[spoiler:Homer believed "Citizen Kang" would have a different ending had Kodos won]].
** [[spoiler: Homer: Don't blame me; I voted for Kodos!]]
* DidntThinkThisThrough: The tub people shrink Lisa in order to speak with their "God"... and have no way to unshrink her again, rendering her powerless to protect them from Bart.
* DownerEnding: All three stories. [[spoiler:Bart is thrown into the attic after discovering he's the evil twin, Lisa is stuck in the micro-city with no way of being changed back to her normal size (what's more Bart steals her project for his own and ''wins'' the science fair). And the U.S (possibly the entire world) is enslaved by Kang and Kodos.]]
* EvilTwin: "The Thing and I" [[spoiler:Subverted; ''Bart's'' the evil twin.]]
-->[[spoiler:'''Bart:''' Oh, don't look so shocked.]]
* GenderReveal: Kodos is apparently ''female''.
* HopeSpot: In ''Citizen Kang'', Homer discovers where the real Bill Clinton and Bob Dole are being held and manages to reawaken them. [[spoiler: Unfortunately, when he tries getting them out of their tubes, [[NiceJobBreakingItHero he instead winds up shooting them up into outer space to their deaths]].]]
* IHaveAFamily
-->'''Homer:''' (to Kang and Kodos) Please don't eat me! I have a wife and kids! [[SubvertedTrope Eat them]]!
* InOneEarOutTheOther: While the miniature spaceships from the "The Genesis Tub" are attacking Bart one of them flies into his left ear and exits his right.
* StockAudioClip: Homer exclaiming "AAHH! Fire! What do I do, what do I do?!" in the title sequence is taken directly from an older episode, "[[Recap/TheSimpsonsS4E3HomerTheHeretic Homer the Heretic]]".
* StupidestThingIveEverHeard: The Frink look-alike laughs at Lisa's idea of unshrinking her.
* TakeAThirdOption: The voters consider voting for a third candidate when Kang and Kodos are revealed, but get mocked for it.
-->'''Kang:''' Go ahead, throw your vote away!
** Ross Perot, Reform Party candidate in the 1992 and 1996 presidential elections, is then seen punching his straw hat open.
* TakeMeToYourLeader: Kang and Kodos to Homer, who explains there's about to be an election.
* UnintentionalPeriodPiece: The 1996 presidential election provides the basis for "Citizen Kang".
* UranusIsShowing: Kang and Kodos tell Homer that they come from "A nearby ringed planet whose name we'd prefer not to mention".
