"Oh, shut up!"
As rude a retort then as it is now. It really doesn't need the "f$%k" in the middle! Say THIS to the wrong person, and you might get something worse than a verbal response.
Lucy said this often. The two eps that come to mind are:
"Mr. and Mrs. TV Show"
When Lucy insists she gets the "full import" of Ricky's refusing to include her in a show, and that she can "take a hint", Ethel replies, "HINT???" Lucy let's loose with her trade mark, OSU!
Ethel's Birthday
When Lucy spies Ethel at the "Over the Teacups" performance, she refuses to sit down, prompting a man holding his seat, "C'mon, Lady, I can't hold this seat forever." Lucy let's loose with another OSU!! Not a smart move to say this to a total stranger.
