Al and Steve buy a beat up Ford Mustang off of one of Kelly's boyfriends. Soon they form a tight friendship while fixing it up like new. The only problem is they are neglecting their wives now that they spend every free minute with the car. Marcy gets to experience something in the backseat of the Mustang that she has always wanted to do and when Al finds out about it, he won't let her forget it.

Steve and Marcy decide that once is enough after they volunteer to watch Kelly, Bud, and the family dog Buck, after Al and Peggy go away for the weekend to a seedy motel in Wisconsin where Al wants to watch a boxing match on the cable TV system.
