After becoming Krusty the Clown's assistant, she quickly rises to fame and eventually takes over as the host of his show. Meanwhile, Homer and Bart delve into coin collecting, with Homer obsessing over a rare 1917 nickel. As Lisa's popularity grows, it inevitably goes to her head, and she starts treating others with arrogance, much like Krusty did. This leads to her alienating her family and friends. Eventually, Krusty manages to regain control of his show by revealing that Lisa's appeal was more about novelty than talent. By the end of the episode, Lisa realizes the cost of her fame and apologizes to her family for her behavior.
