You've all heard the stories about Ozzy Osbourne supposedly biting a head off a bat/pigeon (depending on which version you've been told), right? That's pretty gross - but fairly well known. It's also not really a myth, given that Ozzy has since admitted to doing it! Incredibly, though, incidents involving ingesting flying creatures aren't the most icky thing that Ozzy has been involved with. In The Dirt, Mötley Crüe's notorious biography, Nikki Sixx recites a disturbing tale about the Prince Of Darkness and bodily fluids. Sixx claims that during a joint-tour, Ozzy Osbourne urinated on the ground and set about lapping it up, just to prove that he could. Ew. You'd think that would prove his chutzpah beyond all doubt, right? He hadn't finished though (maybe he was thirsty?!). The Black Sabbath vocalist demanded that Sixx do the same. Sixx, not wanting to disappoint Ozzy, peed on the floor. However, before he could crouch down to mimic his idol, Ozzy beat him to it. Yes, that's right - Ozzy Osbourne lapped up both his own AND Nikki Sixx's urine. It's almost enough to put you off your bat's head and chips.
