In this slim-but-enthralling volume, Ellis Weiner addresses this age-old question and comes to a surprising answer. Guess what it is. Using many of the same arguments-and even some of the same words-employed by people much smarter than he to answer other, even harder questions, Weiner offers a brilliant step-by-step analysis that is as full of insight as it is insightful. His investigation touches on a myriad of topics, including the existence of napkins, the differences between birthday cake and fruitcake, and whether Santa is American.
