An [[AprilFoolsPlot April Fools' Day prank]] leaves Homer in a coma. As the family waits to see if he'll recover, they [[ClipShow recount moments from previous episodes]]...[[LeaningOnTheFourthWall of their lives]].
!!This episode contains examples of:
* AchillesHeel: Homer's is beer, according to him.
* AprilFoolsPlot: Bart's prank for April 1 lands Homer in the hospital.
* BigEater: Homer temporarily recovers from his coma to reach the candy machine, prompting a repeat of his "Land of Chocolate" fantasy sequence.
* ClipShow: The first one, and, as the title suggests, one that the writers had no choice but to do. On the DVDCommentary, they admitted to feeling overworked as Season 4 went on, so Creator/JamesLBrooks suggested a clip show to take the edge off.
* DisproportionateRetribution: The flashback explaining the origin of April Fool's Day shows pagans burning Christians at the stake over a harmless prank.
* EstablishingShot: Lampshaded when Lisa's memory of playing the saxophone for Homer in "One Fish, Two Fish, Blowfish, Blue Fish" cuts to outside the house.
-->'''Mike Reiss:''' Lisa's memory cut to an establishing shot.
* MoralMyopia: Bart, in retaliation for a series of mean spirited April Fools pranks pulled by Homer, [[AprilFoolsPlot finally pulls one over on him]], only to accidentally send him into a coma. After Bart confesses to the prank, Homer wakes up and strangles him. This is just plain wrong, because Homer pulled some harmful if not potentially deadly pranks, including duct-taping Bart's eyes shut and putting milk in the fridge that had been next to a furnace for six weeks yet never apologized. Father of the year material he ain't, that's for sure.
* PoliceAreUseless: Wiggum is content to blow off the explosion at the Simpsons' house... until he learns beer is coming out of the chimney.
* ShoutOut: A reference is made to ''Literature/OneFlewOverTheCuckoosNest'', when [[spoiler: Barney smothers Homer with a pillow, then escapes through the window]] and Music/DonMcLean's song "Vincent".
* StockFootage: The episode is a clip show, thus uses a lot of clips from previous episodes.
* WhatCouldHaveBeen: FOX wanted ''four'' clip shows per season to add more to the episode count and for cheaper the cost. Writers and producers refused, fearing that would alienate fans. The next clip show (the one where Marge wants to talk to the family about romance) wouldn't be until season six.
* WhosLaughingNow: During the flashback explaining the origins of April Fools' Day. The Christians (played by the Flanders) prank the pagans (played by the Simpsons). One angry growl later and the Christians are being burned at the stake.
