Does Santa Claus actually exist? In this hilarious book, this age-old question is addressed and the answer might surprise you. 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.  So, does Santa Claus exist?  Read this unbelievably intelligent (and unbelievably funny) book to find out. Otherwise, no one would ever guess.
