A couple months ago I went to a local theater to see George Carlin. It was sold out but usually there are people standing outside either selling or giving away tix there. Not that night. So I stood outside in the alley with my ear to the door and took in some of his set. I could hear him perfectly clear, and he was on.
I can't think of any comedian quicker, wittier, and more honest. A national treasure for sure.
It just doesn't get any better than this:
