Maggie's 16th birthday is approaching and Fran intervenes in her father's plans for her party. Instead of a boring party at the Guggenheim Museum, Fran convinces Mr. Sheffield to have it at her aunt Frieda's bar. While the place is not nearly as fancy as the museum, Fran has to solve a very important family feud before the party can happen: her mother and Frieda haven't spoken to each other since 1979. The two make peace, but when Frieda comes out of the bathroom, her butt is showing and she blames Sylvia for the same embarrassment when they first fought. They start a food fight which quickly spreads to the whole party in a huge food war. When Mr. Sheffield walks in, he is shocked to see that scene and just when he's about to twist nanny Fine's neck Maggie thanks him for the best party ever.
