The Simpsons (1989): Season 18, Episode 19

18 - 19: Crook and Ladder

Maggie goes on a path of destruction in the Simpsons' home after Marge follows advice in a parenting magazine and throws away her pacifier. Marge finally gives in and sends Homer to get Maggie a new pacifier, but when he can't find the right brand, Maggie comes up with her own substitute - an especially squeaky dog toy. Homer can't sleep through the toy's incessant squeaking and is driven to take sleeping pills, which turn him into a sleepwalker with a penchant for mischief. When one of Homer's sleepwalking schemes leaves the entire Springfield Fire Department debilitated in the hospital, Homer and some of his fellow Springfieldians become volunteer firefighters. They extinguish several fires and are rewarded with gifts, but when the gifts stop coming, they seek other forms of compensation for their heroic acts.
