Season 4, Episode 21: Marge in Chains
In this episode, Marge is arrested for shoplifting after she mistakenly forgets to pay for something at the Kwik-E-Mart. Springfield is a small town, so news of her arrest quickly tarnishes her reputation. Even the town’s most religious family, the Flanders, feels like they can’t trust Marge anymore. When Marge visits their home and leaves to wash her hands, Maude follows and goes into a neighboring room and removing a picture that’s covering a hole in the wall so she can keep an eye on her, much like how Norman Bates watches Marion Crane undress in her motel room in Psycho.
