Claire comes home with the exciting news that she was invited to senior prom. Jay is excited about it and volunteers to chaperone at the dance, in order to keep Claire safe from her date, a senior quarterback. But Jay's exaggerated excitement makes Claire feel uncomfortable, especially when her parents are crowned queen and king of the prom. Michael tells Claire that she shouldn't be upset about it because Jay never attended her own prom as she was giving birth to Junior that night, and so Claire lets her mom enjoy her moment. Meanwhile, Junior falls into another one of Michael's plans once he tries to teach the kid a lesson about money management and ends up turning his car the exact opposite of Junior's plans.
