I was on second, running home on an outfield hit and decided to stop on home base instead of running through, leading to a broken ankle bone.
Played fullback/defensemen in soccer as a kid, with our defensive mantra being "charge and kick it long". Also, everyone loved putting their biggest kid as forward in the junior high bracket. Ball is passed way ahead by other team, lands between me and a big forward, I charge, reach ball, but he reaches me and plows me so hard I get knocked out. I come to, shake it off, take my free kick and immediately walk off the field realizing I have no idea what is going on. I wasn't even sure what direction I kicked the ball. They inform me they kicked the other player out of the game for KOing me and I proceed to bawl my eyes out.
