When there are no parking spots available at the carpool lot, Laird decides to take a handicapped spot and forces Gracen to pretend he can't walk to his office. When a parking attendant discovers the hoax, the guys not only lose their carpool privileges, the bad karma keeps on coming --- Gracen refuses to ride with Laird, and Laird is accused of sexual harassment by Aubrey's favorite babysitter.

Aubrey invites the carpoolers to his daughter's piano recital and Dougie accepts for a reluctant Gracen and Laird, which causes the group to examine their friendship. Meanwhile, with Marmaduke's visualization coaching, a determined Gracen trains heavily to finally beat wife Leila in an annual charity run.

When Gracen refuses to support Marmaduke's newest business venture -- a lawn-cutting business using a flock of sheep -- Marmaduke moves in with Laird, who enjoys being a "dad" to Marmaduke, but this "father/son" bond causes a rift between him and Gracen.
