I had front row seats to one of the last shows he put on. It was amazing! The way edgy comedy works (and not faux edgy like Desperate Housewives or People magazine... real edgy like Howard Stern, South Park, and George Carlin) is that either everything is OK to make fun of, or nothing is. He made pretty offensive jokes about terminal illnesses at the show I attended, and guess what? Not everybody laughed. But nobody walked out.
