Worst injury/injuries you've sustained?

First grade, I was fighting over the front seat with a friend. I got it, and he accidently slammed the car door on my thumb. The LOCKED car door. It was in there a good twenty seconds before someone was able to open the door. My thumb was just shattered. And if my thumb had been about an inch higher, the lock head would have gone through it and I would now be minus one thumb. It was a close call.
