The thing that made this show unique was the way it was introduced by Rob Reiner each week (all be it only six weeks). Acting as if he were presenting a long lost episode of a 1930's/40's comedy team very much like Abbott & Costello, Rob probably fooled a lot of channel surfers into thinking they were actually watching something from bygone days, since all the episodes were filmed in black and white. Perhaps that is why Morton and Hayes was so short-lived. It was probably hard to "get it" if you didn't watch the introduction.
Nevertheless, I was always impressed with Rob's enthusiasm. It clearly demonstrated his love for Bud and Lou, as well as the type of comedy that influenced him in his youth.
