I've broken one bone - my right clavicle. I was sledding in 4th grade, went off a jump, and landed on my neck. I was probably lucky to only come away with a broken collar bone. I broke it on Martin Luther King Jr. Day because we got the day off from school. If the bastard hadn't been shot, I wouldn't have had a broken collar bone. Thanks, James Earl Jones, you asshole.
Everyone seems to think I broke my sister's wrist, but it was her fault.
My left hip was slipping out of the socket when I was in 8th grade. Some whacky genetic disease. Some surgery fixed that. That doesn't count as a broken bone, but I thought I'd mention it.
