Maybe I'm just too old...
I guess I'd like 30 seconds of the TV show, cultural phenomena, or whatever, and 5 seconds of wise-ass commentary. To me, they take each joke too far. Example-
Isaac Hayes doing the hairstyle bit- was it necessary for him to say: "Who knows more about hair than me?" and then rub his bald head?
I'm not looking for a sober, PBS special on the decade- the shows, people and culture are enough to make me laugh. Even Watergate can be made funny. I just don't need to be hit over the head to laugh.
