In Jilin, China, a guy named Ho Lung just went to the emergency room because of a giank knife stuck in his head.  And someone took his photo in the waiting room.

It was so unreal that the doctors thought he was faking, but he told them, quote, "I was playing a silly game with my friend, it went wrong, and I ended up with a knife in the head."  It took a three-hour operation to safely remove it.
