Woody Woodpecker is a classic cartoon character created by Walter Lantz, first appearing in the 1940 short Knock Knock and later starring in his own long-running series. His high-pitched laugh became one of the most recognisable sounds in animation, repeated across decades of cartoons, television reruns and home video. Online, short isolated clips like this one are shared as reaction sounds because they need no context to land. The laugh still works today because it instantly recalls old-school cartoon mischief in just a second.
