Michel Lotito (French pronunciation: ; 16 June 1950 – 17 April 2006) was a French entertainer famous for deliberate consumption of indigestible objects. He came to be known as Monsieur Mangetout (lit. ‘Mister Eats-All’). His digestive system allowed him to consume up to 900 g (2.0 lb) of metal per day. He started eating this unusual diet at age 9.

Lotito’s performance involved the consumption of metal, glass, rubber and other materials. He disassembled, cut up, and consumed items such as bicycles, shopping carts, televisions, beds and a Cessna 150, among other items. It took him roughly 2 years, from 1978 to 1980, to eat the Cessna 150.

Yes, heard of him before. Apparently he was awarded a brass plaque by the Guinness Book of Records, but he ate it.
