"The Otto Show"
322 8F21
Original Airdate: 4/23/92

After seeing Spinal Tap bring the house down (sort of) in concert, Bart decides he wants to learn how to play electric guitar. Playing is harder than Bart thought and he becomes dejected when he sees what a guitar god his bus driver, Otto, is. Because he was too busy jamming with Bart's guitar, Otto arrives late to school and is fired until he can get a new license from the DMV. With no job and no prospects, Otto is thrown out of his apartment and is forced to live in the Simpsons' garage until he can get his job back. Based on their mutual dislike for Homer, Patty approves Otto's new license and Otto is allowed to drive the school bus again.

Guest stars: Christopher Guest, Michael McKean and Harry Shearer as Spinal Tap
