I would not say that fact checking was high on the list of priorities in writing this book. There are many, many errors which are easily found with a quick perusal of wikipedia. This is not to say that there aren't errors on Wikipedia, but there seems to have been some willful ignoring of evidence ...
Funny and tasteless. I consider this a Bathroom book. Ideal for little short reads as necessary!
This is a pretty amusing book that you can pick up and read here and there. Lots of trivia and curious pieces of information. A bit gruesome at times, but fun.
