Thing is, There's a VERY thin line that most comedians nowadays walk--the line between extremely funny and extremely annoying. I find Chris Rock annoying but like Eddie Murphy (well, old 80's Eddie Murphy, anyway). The annoying ones just try too hard to be funny that they aren't.
Which is also why I hate Seinfeld with a passion. He annoys me because he doesn't sound like a comedian--he sounds like a lot of the peanutheads on some forums I've been on in the past which I might not name here (F---NG GAMEFAQS!!!). Seinfeld is not funny, he's just F---ng snide.
