The Simpsons - S11E21 - It's A Mad, Mad, Mad, Mad Marge

Synopsis de l'épisode

Otto has a girlfriend who he plans to marry and Bart offers the Simpson house as a place to hold the nuptials. Becky, the would be bride, confesses to Marge that she doesn't like heavy metal, which is a problem when Otto hires "Cyanide," a Poison tribute band to play at their wedding. Becky moves in with the family and the "hip-female" influence she brings to the family begins to get on Marge's nerves. Selma and Patty convince Marge that Becky is out to get her; Marge overreacts and strikes first and winds up appearing before a sanity hearing. Declared insane, she goes "on the lam".
