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.
Hot but vacuous Laird fears he may be losing his looks when he meets someone who's been dubbed 'the handsomest man' in his office building, so to make himself more interesting to women, Laird starts to take clarinet lessons. In the meantime, while guarding one of Leila's properties, Marmaduke falls for the girl who tagged Leila's flip.
Dougie wins tickets to see his favorite rock band, the Spin Doctors, but Cindy refuses to go because she doesn't trust anyone to babysit their infant; Leila distributes flyers door-to-door in an effort to boost her real estate career, but a typo identifies her as a hooker; and Laird adopts a neighborhood dog who turns out to be a wild, dog-eating coyote.
Laird is infatuated with the sexual harassment seminar leader, Dorrit. To guarantee time alone with her, he claims he's being sexually harassed by the women in his office. Meanwhile Leila enlists Marmaduke's sign spinning skills to promote her real estate business, but he has to out-spin the competitors on the same street corner.
Gracen wonders aloud how his lovely "house flipper" wife, Leila, can afford to buy a $200 designer toaster and how his deadbeat son, Marmaduke, who struts around the house in nothing but his jockeys and a smile, suddenly lands an Internet job making more than his dad. By the end of the day, the guys have their mission: to steal back the respect Gracen deserves by any means necessary.
