Damn that is the funniest thing I've seen in a while. It's a bit long (about 3h45m) but it's really really really funny. He's got some great rants in there. I think I like him better now than I did before just from watching his movies. He comes off as a very cool, funny, and real guy.
If you get a chance to pick this up, and you like Clerks and similar view askew offerings, you'll really like this. It's great.
