Now, some people do this for shock value. Shock is just another uptown word for surprise. Granted it has a different quality to it, but a joke is about surprising someone. I'm a great believer in context. You can joke about anything. I do like finding out where the line is drawn, deliberately crossing it and bringing some of them with me across the line, and having them be happy that I did.
George CarlinPrimitive societies, or social groupings, had shamans, and some of them even more recent in time. Shamans were tricksters. There was a tradition of the trickster, and the trickster was a clown, a humorous fellow. His task was to trick the gods, to humor the gods into laughing, so that there was access to the divine - because laughter is a moment when we are completely ourselves.
