Jimmy’s science project is late, because his parents made him go with them to a Ramones’ concert. When Sean pleads Jimmy’s case with the principal, he only succeeds in getting Jimmy thrown out of school.

Lily freaks out when Sean says they can't afford to send her on a ski trip with her classmates. But things get worse when she learns that Sean inherited some money and spent it on a guitar for himself.

Sean catches a fly ball that's still in play and loses a game for the Yankees. Claudia's upset when the bachelorette party she's throwing for her girlfriend gets disrupted by Sean, Eddie and the boys, who have been chased home by irate fans.

After the family car goes missing one night, the Finnertys find themselves at an impasse: Sean is in mourning over the loss, while Claudia hopes to gain from a slightly inflated insurance claim. But when the battered remains of the car are towed to the house a few days later, it becomes clear that Lily has been covering her tracks about an ill-fated joyride -- and the reason why her parents have to buy the missing parts from Eddie's maniacal mechanic.
