The Simpsons - Season 17 Episode 20

Marge goes on a cleaning frenzy before the housekeeper she’s won the services of comes to the house. One spot remains and she mixes a number of toxic cleaners together to tackle the job. The noxious mixture knocks her out and she wakes up suffering from amnesia. Marge is taken home and the family tries to bring back her memory. She starts to get back memories of her children and other insignificant things, but when it comes to remembering her husband, nothing he does seems to jog her memory. When he can’t get her to remember him, he tries to win her all over again, especially after Patty and Selma get her back out on the dating scene.
