In most episodes, Ted Knight wears different college sweatshirts sent in by fans. In episode 1.15 he wore a white University of Oklahoma sweatshirt and a light blue Northwestern sweatshirt. He later wears a red University of Oklahoma sweatshirt in episode 4.21 and a dark blue Northwestern sweatshirt in episodes 1.7 and 1.17. Probably not a coincidence, Nancy Dussault is a Northwestern alumnus.
