The cult filmmaker, 73, has plenty of ideas about what older people should and shouldn't do. "You can't be trying too hard to rebel [when] you're older," Waters says. He talks about what he was like as a kid, why he's done making movies, and what he wants on his tombstone. His new book about his life in Hollywood is 'Mr. Know-It-All: The Tarnished Wisdom of a Filth Elder.' Also, book critic Maureen Corrigan reviews 'Spying On The South.'
