Homer clones himself with a magic hammock, Lisa's crusade to rid the town of guns resurrects outlaw zombies, and Dr. Hibbert turns island vacationers into animals.

!! Tropes:

* AmbiguousCloneEnding: Subverted.
* BlackIsBiggerInBed: During the gun banning, Lou says this:
-->''"Uh, this always made me feel like a man, you know? Now all I got is my [[spoiler:enormous genitals]]."''
* GettingCrapPastTheRadar: See BlackIsBiggerInBed.
* FourIsDeath: Referenced in Kang and Kodos's token appearance:
-->'''Kang:''' ''(seeing the Island of Lost Souls's skull shape)'' Look at that island shaped like our number four.\\
'''Kodos:''' Makes you think.
* MythologyGag: One of the clones looked like the Homer from ''The Tracey Ullman Show'' shorts.
* PainfulTransformation: Marge into a blue panther.
* TakeThat: [[WesternAnimation/FamilyGuy Peter Griffin]] appearing as [[{{Expy}} one of Homer's clones]].
* TooDumbToLive:
** Homer's clones. When Homer decided to get rid of the clones, he took them to an empty area and asked which ones knew the way back home. After he shot the first one to raise a hand, other clones did it.
** And then after Homer gets rid of them, he then just tosses the cursed hammock out the window, giving the clones the chance to use it themselves.
** And ''then'' Homer himself being the first to chase a donut off a cliff when they (again) get rid of the clones.
* WholePlotReference: "The Island of Doctor Hibbert" is lighthearted parody of ''Literature/TheIslandOfDoctorMoreau''.
* YouNoTakeCandle: The Homer clones talk like this.
