I remember when Richard Pryor said something about how in South Africa, all the black people should pick up guns and kill all the white people, and they went right on with the interview, and nobody stopped him on that. "Oh good old Richard, what a card." As long as you're billed as a comedian, I guess you can say anything.

Things are much more complicated. Feminism versus pornography, for example. There are a lot of feminists who think it is bad, but others think it's good. I have become, you might call it mature — I would call it senile — and I can see both sides. But you can't write a satirical song with 'but on the other hand' in it, or 'however'. It's got to be one-sided.
