It’s from Mr. Rogers’ Neighborhood. There was a puppet show on it, and the puppet King Friday would make pronouncements and then the other puppet characters would tell him, “Correct as usual, King Friday.”
It’s been nearly 25 years since I’ve had a kid young enough to watch that show, but somehow, the phrase sprang to mind as a response to your post.
Cheerio,
Joya
Ahhhhh. I don’t think I ever saw the show as a kid.
