"An X-Ray, made of the stomach of a 62-year-old man who came to the emergency room of Cholet General Hospital in western France in 2002. He had a history of major psychiatric illness, was suffering from stomach pain, and could not eat or move his bowels. Doctors discovered an enormous opaque mass in his stomach that turned out to weigh 12 pounds, as much as some bowling balls. The patient had swallowed around 350 coins, along with assorted necklaces and needles."
