From a vintage episode of The Carol Burnett Show, here's the famous dentist sketch with Harvey Korman and Tim Conway. I'm trying to think of another performer who had their name in the title of an hour-long variety show who would have allowed a 9+ minute sketch that they weren't in on their show. I imagine Dean Martin would have said, "Great! That's nine minutes I don't have to work!" But I can't think of anyone else who wouldn't have fired a producer who suggested such a thing…
Oh, wait. I just thought of someone. The two women who were billed as Pink Lady would have said — in broken English — "Fine. Can you leave us out of the other fifty-one minutes too and let us go back to Japan?"
