Just the facts, Ma'am
Don't embellish your story. Many expressions moved from a movie or television program to popular speech, but none more quickly than a misquotation (as it turns out) of a lines by Sergeant Joe Friday, played by Jack Webb on the 1950s TV series Dragnet. With his deadpan expression and staccato speech, Friday enthralled the public; Dragnet was one of the highest-rated drama series of the decade. At least once in every show, viewers heard Friday tell a female witness, “Just the facts, Ma'am.” Except they didn't. He might have said, “Give us the facts, ma'am,” but he never uttered the four-word phrase. No matter, because the phrase swept the country in a wide range of contexts. If you wanted to be thought of (if only by yourself) as clever, you interjected “Just the facts, Ma'am” delivered in a Friday voice in a question or request. Oh well, Humphrey Bogart's character Rick in the movie Casablanca never said “Play it again, Sam” either.
