This X-ray picture shows a 5-centimeter nail stuck in an unidentified South Korean patient's skull. According to a Seoul hospital, doctors found the nail after the man came to the hospital, complaining about a severe headache. They speculate that the nail stuck in the man's head four years ago in an accident but the man didn't know about it. The nail was removed in a surgery last Saturday. (AP Photo/Yonhap).
