A small and pretty amusing bathroom book about quick shady bets you can make (and sometimes win) with people at your local bar. Each scam is broken out into the set up and the catch with a sprinkling of drawings throughout the book to illustrate some of the finer points.
The book is entertaining for what it is but the author is convinced that the scams are a lot more clever than they really are; I can see a lot of these backfiring. I wouldn't count on any of the scams paying for your lunch.
