I had a pet deer one time and he would do that whenever he lost his horns. He got me in the face one day with his paw while I was feeding him and I hit him as hard as i could hit him with a frying pan right in the nose. I was crying like a baby and he was seeing double. Those paws hurt
This reminds me of the movie where the guy hits the horse in the mouth with his fist....funny stuff.
All kidding aside, surprised it did cut the bejesus out of your face when he clubbed you.
