One time I literally tripped over nothing. I fell really dramatically into the wall and then to the ground and I put my hand out to stop myself and fractured my scaphoid (bone in the wrist). The scaphoid in my other hand got fractured like a year later but not in such an 'Australia's Funniest Home Videos' fashion. =/ I've never been afraid of needles since then because I had to have some nuclear tracer or whatever injected into my wrist to locate the fracture (since the x-ray didn't show it but I was obviously in a lot of pain and not able to move my hand properly) and the dude fucked it up and I was in such pain for 30s that I considered it can never be that bad again lol.
