Episode 8 of "Grounded for Life"
s01e08 Devil's Haircut

Claudia only asks Sean to do one thing, take Henry to the barber before his choir recital that night. But by the time Sean, Eddie, Jimmy and Henry are done going to the movies, getting ice cream and watching a building explode, the barber shop is closed. Sean decides that he can cut Henry's hair himself, but naturally makes a major mess of Henry's whole head. When Claudia sees her son, the guys lie and say that Tony the barber was drunk, and Claudia goes to tell him off. Sean intercepts her, however, and tells her he'll handle it. Finally the truth comes out and Claudia wonders when she became the mom everyone is afraid of. Meanwhile, Eddie hooks Lily up with tickets to a private No Doubt concert, but Lily can't decide who to invite in order to best improve her social standing.
