Dave Barry's Guide to Guys

I was just handed this book http://www.amazon.com/Dave-Barrys-Complete-Guide-Guys/dp/0449910261. From my cursory look - this book is right on the money. The gentlemen who gave me the book said that I would understand guys better, that I may not want anything to do with them, but I would understand them better. I believe him to be true with that statement.
