The Daily Double is a signature Jeopardy! mechanic dating back to the show's original 1964 run: one or two clues per round are hidden, and the contestant who finds one wagers any amount of their score before answering alone. The reveal is marked by a short dramatic sting, which has become shorthand online for any high-stakes moment. Like the Law and Order DUN DUN, it is one of television's most quoted audio cues, and creators often reach for it or the DJ Airhorn when a video needs an instant jolt of game-show tension.
