The Sports Book
Despite many guys' love of sports, invariably some go misunderstood as we bask in the glories of our professional sports heroes. The Sports Book ($24) names itself "The definitive guide to every sport," and it doesn't disappoint. Containing rules and game-winning strategies for more than 200 sports, it will help you become a more well-rounded sports buff, and will no doubt lead to some winning bets over the rules of synchronized swimming when Beijing '08 rolls around.
