Stop Me If You've Heard This: A History and Philosophy of Jokes is the debut full-length nonfiction book written by American philosopher Jim Holt. The book was initially published on 17 July 2008 by W. W. Norton & Company. The text attempts to analyze the history, nature, and philosophical motivation of the joke from the ancient Athens stand-up comics to the today's comedy-club performers, discussing such forms of jokes as racial, political, and sexual humor. The book is based on his 2004 article for The New Yorker.
