Homer wakes up in the snow with no memory of the night before. When he comes home, he finds that his family is missing, Chief Wiggum came over due to a domestic disturbance, and Moe gave Homer a drink called "The Forget-Me Shot," which causes memory loss and is only drunk by people who have a bad memory they want erased.

* ClipShow: A subtle one. Homer's trip through his mind has a TV wall featuring clips from past episodes.
* JourneyToTheCentreOfTheMind
* ShoutOut: The chalkboard gag was "The Capital of [[HannahMontana Montana is not Hannah]]"
** Also, the episode started with [[WesternAnimation/IceAge a squirrel trying to get an acorn]].
* SuicideDare: One of the darkest jokes of the series, where Patty and Selma encourage Homer to kill himself by jumping off a bridge. It's averted when Homer decides to reconsider, but Patty and Selma push him off anyway.
