A
comedian who looked like a
square, but told jokes with a funny, catch-you-off-guard ending, like
dead hookers or whatever.
Then suddenly he got stuck on network TV, ie. Full House, and America's Funniest Home Videos (1990-1997), which somehow made him tell only clean jokes, now he's so...sanitary that people hate him.
He's been breaking out of being typecast by having a cameo in Half Baked, he directed Dirty Work, and has been on the Daily Show "I just wanna strip naked and curse."
He does have a lot of uncredited roles in movies, and did "A comedy salute to Andy Kaufman" (1997). He's also a good friend of Rodney Dangerfield.
Thanks IMDB.com for the film list.
