During a recent visit to David Letterman, Demi Moore revealed that she is a fan of leech therapy. She'd recently had a cleanse in Austria, and part of it involved putting leeches on her belly and letting them suck her blood. "Leeches don't like hair," she explained. "So if you're hairy be prepared to do a little shaving or waxing. They much prefer Brazilian." OK, that's a little more than I needed to know, but CBS decided to see if leeches are the secret behind Demi's good looks. If you're eating breakfast, I advise you to finish before checking out this video. It totally sucks.
