I didn't realise I had put a nail through my brain

Well this weekend I was out with the old nail gun rampaging through the streets and what should happen the damn thing backfires. Now I thought everything was fine but I ended up with a hell of toothache. So I went off to the dentist and discovered a nail embedded in my brain. Well thats kind of the story of this crazy roofer who managed to put a 10cm nail through his brain.
