Plot[]
Told to babysit Maggie by Marge while she goes shopping, Bart and Lisa do a crummy job of babysitting their younger sister. Maggie electrocutes herself by shoving a fork into an electrical socket, falls down the stairs, and climbs onto the roof to catch a butterfly, then falls into a bush with it in her hand. Though Lisa is concerned about the noises Maggie is making, Bart doesn't want to know anything about them.
When Marge arrives home, Maggie returns with the butterfly, which soon flutters away, causing her to cry. Bart complains that Maggie is such a baby.
