Mitch Hedberg. I could always relate to this guy, quite a bit. I really liked his comedy. He wasn't "dirty" or vulgar. I think I first saw him perform on Letterman and kept wondering "Who is this guy? Why am I laughing so much?"
A very good article on Mitch here. It is a shame he couldn't keep it together. It is weird that he's been dead for 2 years already.
I remember listening to him on the Howard Stern show a few weeks before he died. Funny guy. I'm sure there are a ton of videos on You Tube.
