X-Ray of Nail in Skull

David Pescovitz, BoingBoing, writes:

Colorado construction worker Patrick Lawler visited a dentist about a toothache a few days ago. It turned out that a four-inch nail was embedded in Lawler’s skull and he didn’t even realize it. The nail entered his brain through his mouth when a nailgun backfired the week before. After a four hour surgery, Lawler is recovering just fine. From an Associated Press report:

“This is the second one we’ve seen in this hospital where the person was injured by the nail gun and didn’t actually realize the nail had been imbedded in their skull,” neurosurgeon Sean Markey told KUSA-TV in Denver.
