France’s Michel Lotito, better known as Monsieur Mangetout, eats metal and glass for a living. He began eating unusual materials compulsively as a child and has made it into a career, performing publicly since 1966.

Thanks to an unusually thick stomach lining, Mangetout can safely consume 2 pounds of metal a day with no ill effects. Generally he cuts large items — bicycles, television sets, shopping carts, a coffin — into 1-kilogram pieces, which he washes down with mineral oil and plenty of water.

In 1978 he started eating a small plane, a Cessna 150. He finished it in 1980.
