Iwas hoovring the house once, and I had one of the pipe jobbies on the end of the vacuum hose that wouldn't come off, so being the bright 21 year old I was at the time (I'm now 32), i gripped the hose between my legs and pulled the pipe in an upwards motin. Towards my face. Quickly. As it was a Sunday, I couldn't get my front teeth fixed for a whila and was in quite a lot of pain. Lost two front teeth and cracked a whole lot more. Lots of caps and bridges in there now.
