Spilled Coffee Mug

Spilled Coffee Mug

If your job involves meeting a number of new clients at your desk every day, you're in luck. No really, put this spilled coffee mug on your desk behind the monitor (so you "can't see it") and you can play a practical joke on all those unsuspecting people. They will think about the stupid mug and sign any papers you put in front of them, even if it says 'sign here to sell your soul'. Well, at least it worked on me...
