Christine gets angry with Richard when Ritchie gets injured at a skateboarding party. It makes her even more overprotective, and, in doing so, she accidentally runs over Ritchie while he's riding his bike. Ritchie is unhurt, but Christine and Richard argue over who is the worst parent. They finally realize they've actually done a pretty good job. Matthew dates the lunch lady from Ritchie's school. She's very boring, and he's insulted when she breaks up with him because he talks about his ex-girlfriend Lucy all the time.
