"Jokes, paradoxes, riddles, and the art of non-sequitur are revealed with great perception and insight in this illuminating account of the relationship between humor and mathematics."-Joseph Williams, New York Times

"'Leave your mind alone, ' said a Thurber cartoon, and a really complete and convincing analysis of what humour is might spoil all jokes forever. This book avoids that danger. What it does. . .is describe broadly several kinds of mathematical theory and apply them to throw sidelights on how many kinds of jokes work."-New Scientist

"Many scholars nowadays write seriously about the ludicrous. Some merely manage to be dull. A few-like Paulos-are brilliant in an odd endeavor."-Los Angeles Times Book Review
