Claudia tries to throw a bachelorette party for one of her friends; the boys attend a Yankees game and an overeager Sean leans over the fence to catch a ball that's still in play.
Claudia convinces Sean and Eddie to revive their old high school band, and Lily quickly falls for the hunky 17-year-old drummer they add to the lineup.
Sean is jamming with his Les Paul guitar until Eddie arrives and short-circuits the amp; Lily is upset about not being able to attend an expensive school ski trip.
Sean steps back into the boxing ring for the first time in five years, claiming he rejoined to raise money for charity, but he's secretly anticipating his bout with Mr. O'Keefe.
When the Finnertys' sewer line breaks and the neighbors won't let them repair it, Sean has no choice but to call his mob-affiliated Uncle Sal for help.
