Woody Woodpecker debuted in 1940 in the Walter Lantz cartoon Knock Knock, and the character became a sensation in Brazil under the name Pica-Pau, where the dubbed reruns aired constantly on open television for decades. Generations of Brazilian viewers grew up on the bird's mischievous cackle, and the laugh eventually escaped the cartoon to become a staple of internet humor. Today it circulates on soundboards, meme compilations and short videos, used whenever someone wants instant retro comedy with a distinctly Brazilian flavor.
