{Gossip Friday} Mr. Gable Excites Miss Stanwyck
From September 1940:
Movie stars must have their little jokes. When Barbara Stanwyck and Robert Taylor did “Nothing Sacred” on a radio broadcast recently they arranged it so that several lines of dialogue would read thusly:
Bob says: “Is there nothing that will excite you?”
Barbara answers: “Yes, put me in a room with Clark Gable.”
Bob then says: “What’s the matter with Robert Taylor?”
To which Barbara replies: “I never heard of him.”
