Because Mary is desperate for a first date since Wilson with his classmate Brian Heaz, who isn't interested in her, Matt pays him $20 to take her out for pizzas. It actually clicks, but after finding out about the plan the ingrate turns on both good boys. Simon uses his own coaching method to teach Ruthie swimming in the bat tub, to save her embarrassing baby class-lessons, but their parents don't trust it. Eric finds he can't fit his jeans anymore, but jogging only makes him hungry, so he pays Matt to sneak in junk-food.
