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.

Doug and Carrie's friendship with Deacon and Kelly is tested after Doug is distracted and backs into their car.

Arthur is left to fend for himself when Doug and Carrie go on her company retreat with a group of boring lawyers.

Doug's Halloween decorations put Arthur in the hospital; Deacon doesn't like Kirby's choice of a Halloween costume.

In an effort to spend more time with Carrie, Doug hires someone (Nicole Sullivan) to take Arthur for a walk three times a week.
