I had no idea who this guy was until I saw UHF a while back. I thought he was pretty funny and then later he appeared in the Weird Al show (Emo must be one of Al's close personal friends)
twice as a cartoon and a doctor. Later on I saw one of his comedy acts and it was something I've never seen before. It was something like "As a little boy my father asked me if I believed in the lord and I said yes then I stood up and shouted HALLEUYAH (I don't think I spelled that right) and fell off the roller coaster" or something like that. It was kinda weird at first but then I learned to laugh at his jokes.
