This was brought to mind by the “Is Richard Lewis funny?” thread. My nominations:
Martin Mull - He is always described as a comedian, however I have never laughed at anything he has ever said. Has he ever even DONE stand up comedy?
David Brenner - Sure, he is funny LOOKING…but funny? No.
Jay Leno - OK, about 1 of every 100 jokes he tells is mildly humorous, so he could vaguely be considered as funny, but I very rarely laugh during his monologues.
Richard Lewis and Whoopi Goldberg were mentioned in the other thread, and neither of them is or ever has been funny.
The hard part these days is trying to think of a commedian who is actually funny. The Eddie Izzard special on HBO last year is about the only time in the last 5 years I actually laughed at stand-up.
