I’m editing a manuscript about passwords, and need a very quick anecdote/scene from either a famous movie or history that uses the stereotypical challenge-response password dynamic. The current version of the manuscript cites World War II soldiers using “Mickey” and “Mouse” as the challenge and response, which is entertaining, interesting, and almost completely historically inaccurate. I came up with a more accurate D-Day sign/countersign (flash/thunder), but it’s kind of boring by comparison. Anyone have any ideas for something that actually happened in history, or else a famous scene from a movie? It has to be something that doesn’t need much explanation.
I thought of the password scene from SPACEBALLS, but it won’t work in context.
