I’m American. It was in the movie Roger Rabbit, which came out when I was 5 (40 now). And I know I knew it then. I assume I learned it from looney tunes or some other cartoon. But it was ubiquitous enough everyone knew it. To me it feels a little bit like asking how you know who Superman is. It’s just too engrained.
