The Simpsons go to a wonderful new museum. While there, Marge notices what a nice boy Ralph Wiggum is. Marge forces Bart to have a play date with Ralph. Ralph is so stupid and annoying that Bart wants to strangle him. Marge makes him go outside with Ralph. Ralph seems to be a pyromaniac. They go to the Wiggum's residence and Bart finds out that Ralph's father (Chief Wiggum) has a lot of neat stuff, including a master key that will unlock every door in Springfield. Bart goes over for a sleepover and swipes it. He and Ralph wander the town, running into the bullies. Nelson, Dolph, Jimbo, and Kearney take them to the abandoned prison. Bart and Ralph play around with the electric chair, leaving it on when they leave. Quimby wants to show the town the electric chair on the news. He wants to pretend to be electrocuted, thinking that the chair is off. Bart and Ralph see what is about to happen on the news and they have to prevent it. Bart goes to Lisa for a quick solution and she shoots a rocket at the prison which contains an explanation. Instead it goes into Burns' office, and he turns off the power after Quimby has almost beenhuged. Ralph's conscience tells him to burn down the house.

Lisa is the brain of the family and sometimes feels left out because of that. She is an outcast at school because of her talent. Finally there is Maggie the baby.
