American League baseball umpire Ed Hurley appeared as a challenger on What's My Line in this episode from October 4, 1953. In the early days of What's My Line, the panelists were each permitted a 'free guess' as to what the contestant's occupation was. Even though Hurley signed in with the alias 'John Doe,' Dorothy Kilgallen correctly guessed Hurley's job. (Hurley relates a funny story about an incident that occurred that day in the fifth game of the World Series between the Brooklyn Dodgers and the New York Yankees.)
