Brian returns home from his summer in Italy to begin his senior year of high school, what Bill deems "the single greatest year of a young man's life." However, Brian has trouble mustering any enthusiasm for it as he pines for a girl he met abroad. Meanwhile, Perry (James Patrick Stuart) suffers a minor concussion caused---inadvertently---by Linda.

Judy is none too pleased when Bill starts spending every waking minute with their new next-door neighbor, Kyle Polsky (Todd Stashwick), an unemployed brewery heir who, in his endless hours of free time, is putting an eyesore of a Wiffle ball field in his backyard. Meanwhile, Tina is doing a great job of annoying Lauren.
