Tempting Fate / Radio

  • The introduction to the Lux Radio Theatre staging of The Front Page (June 28, 1937), says that Amelia Earhart couldn't make her scheduled appearance, but would be on the show next week after she completed her around-the-world flight. Earhart disappeared forever when her airplane ran out of gas somewhere in the vicinity of Howland Island on July 2, 1937.
  • In the Big Finish Doctor Who drama "The Revolution", after the Doctor has crashed their spaceship and maintained a constant chatter as they slog through the jungle, Benny nearly says "It can't get worse", but then stops herself. When they immediately get attacked by natives anyway, she protests that she didn't say it. "That's against the rules!"
