Michel Lotito - The man who ate an airplane

From the Telegraph : His diet since 1966 included 18 bicycles, 15 supermarket trolleys, seven TV sets, six chandeliers, two beds, a pair of skis, a low-calorie Cessna light aircraft and a computer. He is said to have provided the only example in history of a coffin (handles and all) ending up inside a man. By October 1997, he had eaten nearly nine tons of metal.

Apparently though, bananas and hard-boiled eggs made him sick to his stomach.

Until he died in 2007, France’s Michel Lotito had eaten two pounds of metal every day for more than 40 years, and he still holds the Guinness record for the world’s “strangest diet.” To cement his title, he dismantled a 1,111-pound Cessna 150 airplane and ate it — piece by piece — over two years.
