Mr. D

It's a new school year and Gerry has finally achieved his goal: full-time Phys Ed! But when he finds out how Bobbi's been teaching Phys Ed, Gerry's appalled.

Lisa, now married to Alex's father and still reeling from her Xavier departure, sets out to punish the staff by running for the unopposed position of PTA president.

Gerry meets Ginger, the new DJ at his local gym, and is immediately smitten. In a misguided effort to impress her, he makes up a school dance and offers her a gig as the DJ. Only problem: Robert has banned dances and isn't budging on his position.

When Central High's hockey team crushes Xavier, Gerry suspects them of cheating and he decides to take matters into his own hands. Meanwhile, Bobbi struggles to let go as she prepares for her maternity leave.

Gerry learns that teaching Phys Ed requires more paperwork than he could ever have anticipated. Meanwhile, Bobbi juggles work and a newborn; and a still-vengeful Lisa befriends some fellow moms who may have some helpful dirt on Xavier.
