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.
Claudia tries to bond with Lily by having a girls' weekend in Jersey, but it backfires when Lily runs into two slightly older cool girls from school, Mia and Cindy.
Claudia and Sean return from Atlantic City to find the house trashed, their sons locked in the basement and Lily hauling trash bags full of beer bottles out to the curb.
Claudia returns home from an overnight visit to her mother's to discover Sean has barricaded their daughter Lily in her bedroom after she and her friends went to Action Mountain, an amusement park in New Jersey, without Sean's permission.
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.
Sean snoops through Lily's room and discovers a fake ID, but he and Claudia are hesitant about confronting their daughter because they know they were in her room "illegally."
