I've always been fascinated by the difference between the jokes you can tell your friends but you can't tell to an audience. There's a fine line you have to tread because you don't know who is out there in the auditorium. A lot of people are too easily offended.
I don't understand art-speak. My pictures are big doodles. I'm amazed what people come up with when they look at them. There's one of a figure with two heads that somebody thought must be a comment on the state of matrimony. None of it is a comment on anything.
