Andrei Andreyevich Gromyko (1909 – 1989) was a Soviet politician and diplomat. There is a story that has Gromyko exiting a Washington hotel one morning and being asked by a reporter, "Minister Gromyko, did you enjoy your breakfast today?" His response was "Perhaps." (via Wikipedia)
When I was growing up, my grandpa, a midwestern businessman and sometimes disc jockey, always called me Gromyko.
