Joseph Patrick McEvoy (1897–1958), sometimes credited as John P. McEvoy, was an American writer whose stories were published in the early 1900s. Many were subsequently adapted into movies. McEvoy is probably most well-known for the popular newspaper comic strip Dixie Dugan, based on Show Girl. This quote was taken from his article “Passing the hot potato,” published in The Rotarian in May 1947.
