Chipped a tooth when I was young just jumping bikes, somehow managed to plant my mouth against the handlebars on a landing.
A year and a half ago I busted a hand when I got taken out in a sprint at a road race.. hey I think theres a video of that on youtube somewhere, also received stitches as a result, basically my hand holding the handlebars drilled the metal barriers they like to line the finish with, up until that point I was proud (actually kinda embarrassed) to say I never broke a bone or had stitches before.
haha, Props to the guy who hit a police car AND an ambulance, just a fire engine to go!
