The line comes from Woody Woodpecker, the mischievous cartoon woodpecker created for theatrical shorts and later television, speaking in the cartoon Tragic Magic. In the scene he is too sleepy to stay awake for the show itself, which turns a simple yawn into a self-aware joke about watching cartoons. Clips of the moment have circulated as a short reaction sound for boredom and waiting, because the premise is instantly clear even without seeing the animation. Its appeal endures as a gentle, nostalgic gag rather than a loud meme punchline.
