ER Doc: "Why do you think you have a nail in your head."
Him: "Well....I was working on my roof a week ago and the nail gun misfired and my head hurt afterwards."
ER Doc: "A week ago...surely you would have known sooner than a week later that you have a nail in your head. Are you in any pain now?"
Him: "No just feel like I have something stuck above my right eye."
ER Doc: "Well we can do a CT scan to find out."
Him: "I know its there Doc. I didn't think so but my wife kept saying it was. So she put a magnet to my forehead and it stuck there. See! "
He then pulled a magnet out and sure enough it stuck! The above pic is his actual radiograph. It was lodged just touching his frontal lobe. Neursurgery took him to the OR the next day.
