According to Hoffenberg, Terry Southern and I wrote "Candy" for the money. Olympia Press, $500 flat. He was in Switzerland, I was in Paris. We did it in letters. But when it got to be a big deal in the States, everybody was taking it seriously. Do you remember what kind of shit people were saying? One guy wrote a review about how "Candy" was a satire on "Candide". So right away I went back and reread Voltaire to see if he was right. That's what happens to you. It's as if you vomit in the gutter and everybody starts saying it's the greatest new art form, so you go back to see it, and, by God, you have to agree.
