Your Father Should Know (1)

After Sean confronts Brad's father, who's boasting that Lily and Brad have slept together, he confronts Claudia -- and finds out she already knew too. So when Brad mysteriously gets injured by an airborn Christmas decoration, everyone thinks Sean finally lost his temper. Meanwhile, the boys have spent Sean and Eddie's Liberty quarter collection, and Eddie is disgusted. So Eddie takes the boys out to teach them a lesson about stealing from other people -- by stealing a toy machine that Henry loaded with quarters.
