History Recap / TheSimpsonsS14E1TreehouseOfHorrorXIII

* EndOfAnAge: This is the first Treehouse of Horror to officially be titled "Treehouse of Horror", and, to date, the last to have 3 separate writers, or 3 separate sets of writers, credited for each story, as every subsequent "Treehouse of Horror" episode has only 1 writer credited.

When Homer's hammock breaks, he buys a new one, disregarding the salesman's warning. It turns out that the hammock clones whoever jumps in it. The clones have diminished mental capacity ([[BellyButtonless and no belly buttons]]), but with Homer that's not really very noticeable. Homer decides to send the clones to do his chores, like visiting Grandpa Simpson and shopping with Marge. However, when one of the clones decapitates Ned Flanders, Homer decides to abandon them. He takes them out to a cornfield and shoots any clone that admits to knowing the way back (several do, even after he's shot others who knew). He then abandons the hammock--in the same place he abandoned the clones.

* BellyButtonless: Homer's clones. This is how Marge realizes that the Homer in bed with her is a clone.

* TheBadGuyWins: Ultimately one of Homer's clones successfully replaces Homer, while Dr Hibbert ends up getting exactly what he wants. Though everyone else seemed happy with the later

* BaitAndSwitch: Billy the Kid's zombie gang includes "the most evil German of all time"... Kaiser Wilhelm II. Apparently the undead gunslingers are unaware of world history which transpired since they were buried, and have never heard of UsefulNotes/AdolfHitler.

Kaiser Wilhelm II.[[note]]UsefulNotes/AdolfHitler was born and raised in ''Austria'', though FridgeLogic can set in given that hundreds of other Nazis, including Goebbels, Eichmann, Mengele et cetera, were German.[[/note]]

* ExactWords: While at Moe’s, one of the Hole in the Ground gang members commands Homer to play some “pianee”. Homer begins masterfully playing ''Fur Elise'', at which point he’s told “that’s piano! I said ‘pianee’!”, after which Homer starts playing the sort of piano music you’d associate with an old-timey saloon.

* StealthInsult: [[WesternAnimation/FamilyGuy Peter Griffin]] appearing as [[{{Expy}} one of Homer's clones]].[[note]][[DontExplainTheJoke If you need it explained further, it's saying that Peter is a shallow knockoff of Homer.]][[/note]]
* SurprisinglyRealisticOutcome: Even with the supernatural element of zombie cowboys using the opportunity to invade, Springfield getting rid of all its weapons and guns renders it, in Mayor Quimby's words, ''utterly defenceless''.

* YouNoTakeCandle: The Homer clones talk like this. Bart does the same when Lisa asks if he noticed something wrong with Homer.

* EndOfAnEra: ''XIII'' is the final ''Treehouse of Horror'' episode to be written by three separate writers. Starting with ''[[Recap/TheSimpsonsS15E1TreehouseOfHorrorXIV XIV]]'', one single writer handles all three stories.

* ShoutOut:
** The writers seem to have taken the cloning plot from ''Film/{{Multiplicity}}'', a comedy that has the main character cloning himself to do some of the tasks and obligations of his workaholic life. It also includes the InUniverse rule not to make a copy of a copy, as they get progressively dumber when that happens.
** The second Homer that arrives via time travel wears all kinds of futuristic apparel that resemble the stuff seen in the 2015 sequence of ''Film/BackToTheFuturePartII''.

* WholePlotReference: ''The Island of Doctor Hibbert'' is an {{affectionate parody}} of ''Literature/TheIslandOfDoctorMoreau''.

* UnwittingInstigatorOfDoom: Homer's "magic hammock".
