I broke both of the bones in my right forearm playing football. I didn't notice at first until I tried to get up and my forearm bent way too far (incidentally, an easy way to tell if your forearm is bent too far is if it's bent at all
). Now I've got a rather unsightly scar on both sides from when they cut in to reset the bones. If people ask, I like to have some fun with it, saying that I got it wrestling a polar bear or something of the sort; makes for a fun icebreaker.
