George Carlin - HE KICKS MAJOR ASS!!! I have his live shows on my computer. Bill Maher - I love his show... he isn't as funny, but he makes for great arguments. Dennis Miller - RIGHT WING FUCKJOB. They're all dickheads. But I love 'em.
I actually saw George Carlin live, when I was 15. He's awesome..you need to read his books, they're full of witty, intelliegent comments. I find myself agreeing with almost everything he says. I'm not a big fan of Bill Maher, but I love his show on HBO (also loved Politically Incorrect, but Real Time is even more "politically incorrect") because he has people with all different viewpoints on it. This year's season premiere was great, him and Michael Moore totally made an ass out of that Republican senator, and I LOVED it when they begged Nader to drop out of the race!! Dennis Miller.....eh...never found him to be very funny, and he is too conservative for my tastes. He was funny on SNL though.
My favorite Bill Maher quote is this: "You do realize that you're being represented by bunch of soul-less cash whores, right?"
