The problem arose when the clumsy clot lost his balance and fell over. As he explains 'I heard the gun go off. I felt a pain in my chest, so I went to take off my jumper, but I couldn't because it was nailed to my chest.' Ouch!

It was later revealed at hospital that the nail was an inch inside his heart, and a single millimeter away from the main artery. In the most shocking, and most stupid, aspect of the story, the man actually considered removing the nail with pliers before dialing 999. Certain death would have followed.
Best left to the professionals you might say or maybe not as a 17 year old working on a building site in Australia recently shot himself in the head with a nail gun.
Mind how you go now.
