I was watching "The Jack Benny Program" on Antenna TV. The guest was Carol Burnett. She was on stage with Jack and one of the jokes she said is that if she had her way, she'd like to have major changes to Jack's program. She continued..."For instance, I'd like to have you come out from behind the curtain in the middle of the stage, instead of that looong walk you make from the side." Jack asks, "Well, why is that?". She says it's because other Hollywood actors and actresses are now doing the same thing. Jack asks, "Like who". Carol responds "Loretta Young"... laughter ... Jack shakes his fist and says "Now, cut that out!". I don't get the joke since I don't know much about Loretta Young. Help, if you can.
