Marge goes too far in cleaning the house and passes out after inhaling too many cleaning solvent fumes. When she wakes up in the hospital, she has amnesia, which is seemingly cured when she recognizes herself and her children through her quirks, but doesn't remember Homer at all.
Tropes that apply to the episode
- Animation Bump: Homer moaning◊, which has more in-betweens than usual for the show.
- Call-Back: Homer punching George H. W. Bush in "Two Bad Neighbors".
- Comically Missing the Point: Marge desperately cleans her home to keep a cleaning lady from seeing how dirty her family is.
- The Constant: Homer's alcoholism. Saying that he did was the only thing that made Marge remember him for good.
- "Could Have Avoided This!" Plot: Homer is annoyed that he wasted so much time trying to get Marge to remember him when just mentioning beer would have done it.
- Darkest Hour: Marge forces Homer out of the house and breaks up with him.
- Easy Amnesia: Played both ways — Marge gets total amnesia that she was ever married with children from a bonk to the head, but the only thing she doesn't recovers within five minutes of this being said is her memory of loving Homer.
- Halfway Plot Switch: The episode opens with Bart and Milhouse painting the house numbers of Evergreen Terrace for money but not finishing the Simpsons' address because Homer didn't want to pay them.. which leads to a case of mistaken identity wherein the Simpsons get the mail from a couple in one of the other houses.. which leads to them getting a notice they "won a contest" and some maids will be visiting to clean their house for free.. which leads to Marge frantically trying to clean the house to prevent gossip and getting amnesia because the fumes make her hurt her head.. which leads to 20 minutes of Homer trying (very badly) to regain her love because it was the only thing the amnesia totally erased...
- Imagine Spot: Marge has one with three Irish cleaning ladies gossiping about her family.
- Jerkass: The guy Marge dates from the service doesn't hesitate to dump her after being told she has amnesia and has three kids. Even when Homer rightly calls him out on it, he doesn't seem to care.
- Logical Latecomer: A more complicated example than usual "thanks" to Easy Amnesia, but when Homer tries to restart Marge's memory of him by describing some of his more outrageous (mis-)deeds like being an enemy of the Bush family, Marge's reaction is to be horrified.
- Noodle Incident: Homer punching George Bush, Jr (though Homer beating up George Bush, Sr. was well-documented, as seen on the season seven episode "Two Bad Neighbors").
- Obnoxious In-Laws: Patty and Selma exploit the fact that Marge has forgotten about Homer to make her meet other men in the hopes she will dump him for good.
- Take That!: Homer's excuse for opening (and eating) other people's mail."All our mail's ever brought is bad things: bills, jury duty, Entertainment Weekly..."
