I got a nail almost through my hand, it was one of those iron rusty ones too. i was about 6 or 7 when this happened.
I was playing kick-ball with some of the kids in my class, i ran up to pick up the ball, then this dumbass runs up to me and tries to kick the ball before i could pick it up, i picked it up but he kicked my finger, jamming the motherforgeter.
the rest of the entire week i could not move it, it was swollen.
same thing happened to me recently but i was playing football with my friends. i ran up to catch it and the football hit my finger, jamming it. felt horrible.
