Bill Hicks wasn't a stand up comedian because he never told any jokes. None of his material had punchlines, or even moments where you suddenly realise he's been spinning a yarn  or making a convoluted observation  just so he can get to the point where he'll give it an unexpected twist to jerk a reaction out of the audience. All he does is just stands there and tells the truth. And the truth is so wrong, and disgusting, that you just feel inwardly grateful that someone, somewhere realised it as well, and managed to make it funnier than it probably deserved to be.
