While I love the Cosby/Culp Newhart dream takeoff idea, a variation would find Cliff and Clair waking up and sharing a dream, that they were still married to people that looked like them but were entirely different, as on Cosby’s later CBS sitcom, Cosby.
It would have been awesome if this was the last scene. Probably would have pissed a lot of people off though.
Ah, I love that scene and I do miss that show. Bill Cosby could really deliver funny, yet somehow sincere, dialogue.
