This reminds me of an episode of
I Love Lucy. Lucy had hired an English tutor to teach her, her husband and the Mertzes perfect English. One of them happened to say "OK" to the tutor, and he recoiled and announced that they must all rid their speech of slang. He added, "There are two words you must never use. One of them is 'swell' and the other is 'lousy.'" The pupils didn't quite catch his meaning, and Fred Mertz said, "Well give us the lousy one first." Moments later, Lucy accidentally uttered "OK" and then quickly corrected herself: "Oh, I would say 'OK' - that's a swell way to get off to a lousy start."
