“The Otto Show” is the twenty-second episode of Season 3. It first aired on April 23, 1992. It was written by Jeff Martin and directed by Wes Archer. Spinal Tap guest star as themselves, reuniting Simpsons regular Harry Shearer with Christopher Guest and Michael McKean. Otto loses his job driving the school bus, partially because he doesn’t have a driver’s license, and, after being kicked out of his apartment, goes to live with the Simpsons.
