Being a well trained and experienced neurosurgeon, I immediately noticed a dull grey nail protruding almost one centimeter out from Mr. Jones’s head. The shaft had pierced his scalp through his fine and neatly trimmed hair immediately behind his left ear. The remainder of the eight centimeter spike was embedded in his parietal lobe. Congealed blood encrusted his pinna and coated the side of his neck. Aside from disorientation to place and time, he was in good neurologic condition.
