If you're the "fun" guy in your office (and I'm guessing you are), you'll love the Phantom Keystroker. This little USB device is sure to drive anyone who has it hooked up to their machine insane: it randomly moves the mouse around and types out garbage text at random intervals, making the victim think their computer is busted and making work near-impossible. Sure, it's a little mean-spirited, but you're so good-looking there's no way anyone can stay mad at you. Right? [Product Page]
