Initially unwilling, Bart discovers that Ralph's father, Chief Wiggum, owns a key that opens every lock in Springfield. The two go out at night and open many places to have fun, but soon encounter bullies Nelson, Dolph, Jimbo, and Kearney. The four pressure Bart and Ralph to sneak into an abandoned prison, but Bart decides not to when he sees that Ralph is scared. The key is thrown over into the prison by the trouble-makers, causing Bart and Ralph to go retrieve it. While in the prison, the two find an old electric chair, which they turn on to see if it still works, and later go home. The next day, Mayor Quimby announces the prison is reopened, and decides to demonstrate what criminals could face by sitting in the, unknown to the police and the mayor, active chair. Bart rushes to Ralph for help to tell the mayor that the chair is active, leading Lisa to fire a small rocket with a note attached to the prison. The rocket misses and crashes into the power plant. Mr. Burns responds and, upon realizing the prison has been using free electricity, turns off the power, saving the mayor.[39]
