Agreed on Dennis Miller, even more so on Norm. Dude was awful. I loved Dennis because he was obviously intelligent. I was one of the few that actually enjoyed his time on Monday Night Football, too. His references were so obtuse and obscure, but if you understood them it was FANTASTIC. Norm's delivery was awful, so much so that the audience wasn't sure when to laugh, so he would repeat the dumbass punchline until they would pity laugh. Reminds me of the dorky kid in school that would tell the same joke over and over again until someone threw an eraser at his face to shut him up.
As for Chevy Chase live, no, I never saw that either, but my dad was really big on them and we would watch old "Best of..." segments on them and Johnny Carson whenever they were on.
Good times.
