I'm sure that many people remember the familiar tune of the ice cream truck from childhood. I can recall always pleading with my parents to "give me a dollar" upon hearing that intoxicating sound, so that I could go and buy myself a Rocket Pop. My childhood memories of the ice cream truck have been officially ruined! According to a fascinating piece on NPR, the tune comes from a 1916 song called "Nigger Love A Watermelon Ha! Ha! Ha".
"Nigger Love A Watermelon Ha! Ha! Ha!" merits the distinction of the most racist song title in America. Released in March 1916 by Columbia Records, it was written by actor Harry C. Browne and played on the familiar depiction of black people as mindless beasts of burden greedily devouring slices of watermelon.
