Remember those activity books that were supposed to distract you for hours on end during those endless cross-country vacation drives with your family? If not, then consider yourself lucky. The good news is that the masterminds at Nerve.com have created Where's Dildo?, the grown-up equivalent of those books, and it's a hell of a lot more fun. Contained within the book's spiral-bound 200 pages are naughty word finds, puzzles, quizzes, and other mischief, divided into easy, medium, and hard chapters. Our favorite: "Spot the Difference" featuring a buxom, whip-toting dominatrix. Who's up for a drive to the Grand Canyon?
