Plot summary
Cliff and Clair look forward to a visit from their old friends, Scott and Jill Kelly - played by guest-stars Robert Culp and Ann Reinking. Clair knows how foolish Cliff and Scott act when they're together, though, and gives Cliff a warning. The two pranksters must promise to behave themselves and act like grown men - not silly boys - when the foursome dine at a fancy restaurant. Also, Theo and Cockroach contemplate shaving their heads so they can appear in a new hot music video.
