Doug Heffernan puts in a long day's work delivering parcels and comes home each night to his loving wife, Carrie; unfortunately, he also comes home to his wacko father-in-law, Arthur.

Ray (Ray Romano) invites Doug to play golf at an exclusive country club; Marie (Doris Roberts) teaches Carrie how to clean a house.

Doug is disappointed when Carrie isn't jealous of his beautiful trainee; Arthur feels he's been scammed when he orders a gravestone.

Doug convinces cousin Danny (Gary Valentine) to take Arthur for the weekend; Doug is hit by a baseball and meets a new friend (Bill Cosby) at Dr. Becker's (Ted Danson) office.

Carrie befriends her annoying neighbors so that their week at a Hamptons time-share does not go unused; Arthur develops a nasty rash.
