Let's see... Where do I start on this?
When I was about 3 I was at a party at my grandmother's house. She lived in a housing community where the visitors' parking lot was next to the basketball court, but the court was actually some 6 feet below the level of the parking lot, and the embankment between the two was covered in round river rocks. We were in the process of leaving, with the adults having a post-party get together outside the car, so I started playing with my grandmother's dog. I pretended he was a horse, straddling him and walking with him. Suddenly, he heard some dogs barking on the other side of the basketball court and shot off toward the dogs, with me in tow, my head bouncing on the rocks all the way down the embankment. I don't know what hurt worse: falling down the embankment, or having my uncle, who happens to be a doctor, stitch my head in my grandmother's living room 10 minutes later.
Here's one from when I was 9. There was a rusty, old fence that divided our property from my friend's property at the place where I lived. There was a big hole in the fence which my friend and I used as a doorway between our houses. One day I was crawling back through to get to my house because it was dinner time and I got my knee caught in the fence. It wasn't a regular little scratch that anyone can get while crawling through a fence; I could actually see the bone and the tendons. My mom took me to the ER, where they basically told me to go home. They said that, since it was in a place that didn't have too much flesh and moved constantly, the best thing to do was bandage it up and not stitch it.
I've never had any broken bones, but I dislocated my wrist when I was about 11. I fell off my bike when my friend collided with me as we were racing, and, when I got up, I saw that my right hand was shifted 2 inches to the left of where it normally would be. My friends helped me pop it back into place and I never told my mom about it. That actually gave me a neat little trick that I like to show off frequently: I can dislocate my wrist, quite audibly, at will.
The last one that I'll talk about happened 3 weeks ago. It wasn't exactly gruesome, but it really sucked and it kept me out of work until this morning. We were using a forklift to put a 400-pound stack of truss on a truck. When the forklift raised the truss, the load shifted and came down on my collarbone. No fracture or anything, but it hurt like hell for 2 weeks.
