Ernie Mayne (17 March 1871 – 15 May 1937) was an English music hall entertainer. Born Percy Ernest Barratt in Topsham, Devon, by the age of ten he was living in London's Soho. He weighed about 20 stone and sang comic songs such as "Fried Fruit Fritters" about his weight. Mayne first gained interest in comedy when people laughed at him for wanting to be an airman, because of his weight. One of his songs, "What D'yer Think of That" can still be heard today, as it was later remade as Lonnie Donegan's song "My Old Man's a Dustman".
Mayne died in 1937. at the age of 66.
