Playing with a tooth in his forehead.

Brisbane rugby player Ben Czislowski found out his headaches were caused by a tooth (from opposing player Matt Austin) that had been lodged in his forehead since April first! The original wound was stitched up, but the embedded tooth was apparently missed at the time. Or not missed, on Austin’s part.

"I've got the tooth at home, sitting on the bedside table," he said. "If he (Austin) wants it back he can have it. I'm keeping it at the moment as proof that it actually happened."

Czislowski had been competing for four months with the extra tooth in his head. http://www.iht.com/articles/ap/2007/07/17/asia/AS-ODD-Australia-Embedded-Tooth.php -via Arbroath
