The Los Angeles Police Department announced this morning that they are testing a knife once found on property owned by the relatively unknown accused murderer O.J. Simpson.

A Canadian man who finally got a good handle on an annoying itch he'd been scratching at for the past three years accidentally uncovered the source of irritation: A knife blade that got stuck in his back in 2010.

Do you have splitting headaches? Yes, sure, they may be migraines, or, you might have a four-inch knife, buried in your brain, for four years. Li Fu, a Chinese gentleman who had been complaining of headaches, recently discovered that the source of his pain was, yes, a four-inch knife, "stuck in his brain for more than four years." Apparently, doctors who treated him in the wake of a stabbing during a robbery in 2006 "failed to notice the knife buried deep in" Mr. Li's skull; later, apparently more competent doctors decided to perform an X-ray, and, lo: A knife, "buried in his face," in the Daily Mail's immortal phrase. Li underwent surgery and had the gross little thing removed. He is now in stable condition. [Daily Mail]
