John Waters is the writer and director of such cult classics like Pink Flamingos, Serial Mom, and his biggest mainstream success, Hairspray. He’s been making movies since the 1960s and this year he released his debut novel, Liarmouth: A Feel Bad Romance. The novel is an incredibly dirty romp filled with the kind of taboo storytelling that John Waters revels in. In his work, he shines a light on the worst of us but rarely to ridicule, more as a reminder of how gloriously sinful we can be, as we discussed when I spoke with him in his Manhattan home. His interest in the carnal, though, has its limits. “When I got a colonoscopy, they said, do you wanna watch? No!” he told us. “Why do I wanna go on a fantastic voyage up my a–hole?”  We also talked about money management, aging, and his secret to maintaining his many long friendships. “I do stay in touch and if anything bad happens to you, I call. If you get a bad review, I call. If you go to jail, I definitely am your first visit,” he laughed. “I never don't come visit you if you're in jail.”
