See the X-Ray of the man to the left, the one with the knife in his skull? Local fellow. He survived that incident, and was in fact conscious during the extraction process. That story made an episode of one of the emergency room trauma shows a couple of years back. Then he sued for using his story.
I would call that kind of story public domain, although I was not blessed with a noggin that fricking hard, or brain tissue that insolent to intrusion. If I were, I'd probably want to do a Joseph Merrick thing, and charge money at the Coastal Empire Fair so people could see someone drive a blade in my skull, then leave the last one in while I went spree-drinking.
It wouldn't be the first time I'd made a poor choice.
