The strange and interesting story of Le Pétomane:

Joseph Pujol was born in Marseille. He was one of five children of François (a stonemason and sculptor) and Rose Pujol. Soon after he left school he had a strange experience while swimming in the sea. He would put his head under the water and hold his breath whereupon he felt an icy cold penetrating his rear. He ran ashore in fright and was amazed to see water pouring from his anus. A doctor assured him that there was nothing to worry about.
