I had a great time on News Radio, I got to make tons of money in relative obscurity and learn a lot about the TV biz and work on my standup act constantly. It was a dream gig.
I had seen movies before that that had made me laugh, but I had never seen anything even remotely close to as funny as Richard Pryor was, just standing there talking.
The misconception is that standup comics are always on. I don't know any really funny comics that are annoying and constantly trying to be funny all the time.
