"When You Dish Upon a Star" is the fifth episode of Season 10.
Keeping Hollywood secrets proves difficult for Homer when he scores a personal assistant job for the husband and wife celeberties, Alec Baldwin and Kim Basinger. Ron Howard and Brian Grazer also guest star.
The Simpson family plans to spend a day at Lake Springfield, where Homer soon gets involved in a parasailing accident, crash landing in the bedroom of Alec Baldwin and Kim Basinger's holiday home. He convinces them that he should work for them as a personal assistant, while keeping it a secret that they are in Springfield.
Eventually, Homer becomes good friends with the celebrity couple, although he creeps out the visiting Ron Howard and tries unsuccessfully to pitch a script about a "killer robot driving-instructor that travels back in time for some reason" and a talking pie.
Eventually Homer's inability to keep a secret leads Baldwin and Basinger to mistrust him, and they end the friendship. In retaliation Homer starts a mobile museum of "Hollywood Jerks" displaying their personal belongings to get back at them. The celebrities discover this while intending to apologize to Homer. A high speed chase ensues between Homer in the mobile museum and the celebrities in their Hummer H1. Homer agrees to stop after Ron Howard is injured during the chase.
