um... mine would probably have to be a tie between when I was riding my motorcycle and I hit a gravel patch, stopping the bike, but sending me over the handle bars at 30 mph, i messed up my arm pretty bad and still have the scars to prove it. or when I tried to dive for the first time, and when I hit the water my body folded (feet touched head) doing something to my back, and i couldn't move for a few days.But I'm all fine now
