 Bart has a big outburst at a funeral for Homer s dead Vegas wife. He is therefore brought to a doctor who prescribes him a drum kit to focus his energy positively. Lisa brings him to a jazz club, but then ends Lisa s dream to become the best jazz musician. Bart joins a famous jazz duo and makes it a trio while Lisa starts caring for stray and outcast animals. But this plan turns bad when a tiger bites Bart and he is unable to drum. A benefit concert is held to raise the money for a surgery that could save his new hobby, but instead, he uses the money for a lost animal shelter in Lisa s name.
