Richard Arthur Assman (February 14, 1934 – August 15, 2016) was a Canadian gas station employee whose name propelled him to celebrity status across North America for four months in 1995.

Over the weeks, Joe Namath declared himself an "Ass-maniac", while Assman received a musical tribute from Tony Orlando[3] on Letterman: Northgate Petro-Canada Oh, they're relocating Their new office at Victoria Square They're celebrating Oh vaya con dios, Dick Assman Vaya con dios, my love As his fame grew,[4][2][5] Vancouver polling company Angus Reid Public Opinion reported that 49 percent of surveyed Canadians in September 1995 had heard of his name.
