Preparations are under way for the arrival of a new guest star, Sylvia Hudson, the most important female star in the pioneer days of television. The hope is that if things go well, more big name stars will want to appear on the Lester Guy Show. Sylvia also happens to be Betty's cruel sister, who always makes fun of her. There's another guest star as well: Mr. Peanuts, the star of the morning kids show. Betty is upset over the arrival of her sister, Lester is excited because he once had a relationship with Sylvia (or so he tells it). Sylvia arrives, orders everyone around and is just generally rude, including insulting Mr. Peanuts. Everything goes wrong on the show of course. Nicole's skirt gets caught in the gears that open the door during Sylvia's entrance, causing them to slam shut in her face. Sylvia spends the most of the rest of the show in a daze, passing out during the next sketch. Betty, Bert and even Mr. Peanuts try to save the skit by taking over Sylvia's part. Sylvia finally comes to in just enough time to ruin the scene and threatens Mr. Peanuts on live national television in the process. Everyone sings the Mr. Peanuts theme song to cheer him up, and Sylvia ends up getting the door slammed in her face again.
