I am interested in comparative religions and scholarship of religions. This book caught my eye as an amusing and informative read. It is amusing, but it shouldn't be taken as a definitive source without fact-checking. (I'm afraid I am unyielding on the importance of fact-checking, and not by quoting Wikipedia!) I found several mistakes, which I fact-checked to be sure. All-in-all, this is a light read if you don't care over-much for accuracy. Just know what you are getting.
Great fun for anyone interested in trivia,facts&curiosities wanting to laugh.
