I told a few people at the last game about this very odd airsoft injury. This guy got hit in the ear at a really strange angle and the bb stayed in his ear lobe. I couldn't find the original pictures, but I did find this thing in the rules webpage of the place where this happened.
It is the first and third picture on the bottom row; one was with the bb in and the other was after they popped it out. There's a few other nasty pictures too.
