The only thing more fun than electrocuting college students? Making them so bored that they electrocute themselves.

In one of those experiments that make you wonder if the professors were just getting payback for student reviews, researchers from the University of Virginia put their freshmen in a room for 15 minutes to be "alone with their thoughts." They also left them hooked up to a cable that would administer a mild electric shock if they pushed a button. Sure enough, more than half of the men, and a quarter of the women, went ahead and zapped themselves. It turns out, most people would literally prefer being electrocuted to being bored.
