The book is exactly what the title implies - a rundown of American Presidents and strategies on how to beat them in a one-on-one fist fight. Needless to say, it was highly entertaining. You will definitely laugh, if you have a sense of humor that is.
I listened to it on audiobook and I had a smile on my face the entire time, occasionally laughing hard. It was a welcome break from all of the other serious titles that I've listened to, read and reviewed. The voice actor did a great job in representing the satirical nature of the author's work. The author, in turn, did a good job of separating his satire from real facts.
I wouldn't use this book as a definitive source of information, but the information contained in it does appear to be accurate, as far as I can tell. My only disappointment was that it ended with President Reagan, and skipped President Jimmy Carter. However, I do understand why. It wouldn't be wise as it might be taken as incitement of violence against living public figures. So the author probably didn't want to deal with Secret Service inquiries and such.
In conclusion, if you enjoyed drunk history series on the history channel or you haven't and are simply looking for a laugh, I'd definitely recommend this title for you.
