'The events described in these stories are real," humorist David Sedaris wrote in the introductory note to Naked, his 1997 collection of nonfiction essays. The New York Times was convinced: When Naked hit the best-seller list, it categorized the book as nonfiction. The Library of Congress called it biography, and Sedaris assured several interviewers over the years that the book was essentially factual. "Everything in Naked was true," he told the webzine Getting It in 1999. "I mean, I exaggerate. But all the situations were true." Great.
