When Bart turns a quiet funeral into a chaotic mess, his parents are faced with a mob of angry Springfieldians who have had enough. Homer and Marge desperately look to a child psychiatrist for help, who suggests that Bart take up drumming to channel his energy. Before long, Bart is laying down fills like a pro, getting into drum-offs with The White Stripes, and jamming in a band with Lisa's favorite jazz musicians. It doesn't take long before Lisa's encouragement turns to deep-seated jealousy, forcing the Simpson siblings to learn how to march to the beat of the same drum.
