Coincidentally I just learned where the name Jon Arbuckle came from. Jim Davis had heard the name of Yuban Coffee’s founder, John Arbuckle, and thought it sounded funny and distinct enough to base his comic around. I only found this out because of a video explaining the joke on “Airplane!” about the wife having an inner monologue that “Jim never had a second cup of coffee at home…” which was a well known Yuban commercial at the time.
