This book would not have been possible without the help of others. First, my thanks to the many minds that have created and shared the bets, including Martin Gardner, Mel Stover, Alex Conran and Paul Wilson. Thanks also to those who have kindly provided additional information, including Alom Shah, Bill Kalush, Gordon Rutter and Bernard Carr. Special thanks to David Britland for his help and guidance, Jeff Sanford for trying everything out, and Caroline Watt for her unending support and patience. Finally, I would like to thank my editor Robin Harvie, agent Patrick Walsh, and the millions of people who have been kind enough to watch my Quirkology YouTube videos.
