How many bones have you broken or fractured and was it your own fault?

Over my life I have been in some pretty hairy spills and such but have never broke a bone, the close I came was playing soccer in the rain on Astroturf, I went for a ball the same as another player and he got more of it sending me tumbling; I fractured a knuckle though I didn’t learn of it for some time after. When I was a kid and teen all the nasty bike spills, falling down hills hiking, jumping from roofs, trees and other high places it amazes me I never broke anything while others I knew broke stuff tripping on the stairs.

How many times have you broken something and what did you break? Was it a work accident, sports thing or something else you could not foresee or were you doing something kind of stupid like trying to launch your BMX bike over a parked VW or something where you knew there was the possibility it would not turn out well if you missed?
