Road Runner is a Looney Tunes character who first appeared in the 1949 short Fast and Furry-ous, built around a simple chase in which the speedy bird always outruns Wile E. Coyote. The beep beep became the character's calling card, a sound audiences could recognise even before the bird appeared on screen. Through decades of television reruns, home video and later online clips, the call moved beyond the cartoons themselves and became a general shorthand for a fast getaway. Editors now reuse it whenever a quick exit needs to feel playful rather than serious.
