Like a few country stars on this list of cameos on The Simpsons, Dolly Parton saves the day in her episode. Homer and his friends travel to the Super Bowl, but end up getting tossed in the stadium's jail after sneaking into the game (their tickets were printed on crackers). The country star frees them by dissolving the lock with her extra-strength makeup remover. From there, they go to a stadium suite and eventually to the locker room to celebrate with the winning team. This is one of the most bizarre episodes of all time, with broadcasters John Madden and Pat Summerall even panning one of the gags. Parton is magnificent, of course.
