Now that scriptwriters pepper dialog with indiscriminate f-bombs, it's hard to believe that once upon a time movies had to watch what the characters said; when Rhett tells Scarlett, "Frankly, my dear, I don't give a damn!" it was denounced from pulpits across the nation. So it's interesting to see some of the older movies which depended on wit and artifice to communicate something in a way which could sneak by the censors. One of the more famous ones was in The Maltese Falcon when Bogie refers to the Elijah Cook, Jr. character as a gunsel. That sort of sounds like a gunman (and Dashiell Hammett depended on that ambiguity to sneak it by the censors) but the word refers to a young man kept by an older man for sexual purposes. And sometimes they depended just on juxtaposition of phrases which created a double-entendre. My favorite one of this genre is Groucho in Animal Crackers introducing a song by Chico: "Signor Ravelli's first selection will be 'Somewhere My Love Lies Sleeping' with a male chorus." What are your favorites?
