Playing woodsball at my local field. Go to slide into a bunker and my foot catches on a root, turning my slide into a somersault. Tore my medial collateral ligament, which didn't hurt as much as going through the bunker did
Forgot to bring socks to a tournament. Seven games on sandy fields pretty much removed all the skin from my ankles. Painful and pretty gross. One of the few times I was glad not to make finals.
Reffing open class in the woods at my local field. I'm running down the tape to check someone on the other end and tell this nice british chap (with an Angel, of course) to hold up while I go past. Guess he didn't hear me because he let fly with a nice string just as I passed his tree... five shots to the head from about two feet away. Damn near knocked me out. Although hearing him exclaim "Bloody hell, I've killed the marshall!" was pretty funny.
