Query: One of those fun 'bet you didn't know' books

It always amazes me when people go nuts in reviews with respect to books like this. If you are looking for a book where you can pretty much pop it open anywhere, read, smile, and toss a fact into the back of your head, this one is it. You will interesting data points from history, things to give you a smile and even a few things about people that will flip something you thought, 180 degrees. It's a fun book, not a text book, so enjoy it.
