The line comes from Woody Woodpecker, the long-running cartoon woodpecker, in the episode Teacher's Pet from The New Woody Woodpecker Show, where a tired Woody wakes to find something unexpected happening around him. Short reaction clips from classic cartoons have become popular on soundboards because they are instantly recognisable even without the picture, and this one is often shared alongside the Woody Woodpecker Laugh for sleepy, confused or caught-out moments in edits and memes.
