Gossip Friday: The Great Mouse Detective

From 1946:

It happened at a beach resort up the coast, where Clark Gable was spending his holiday. In the middle of the night he beard a strange noise in his room. It stopped, then grew even louder. Clark finally called down to the desk and asked them to send up the house detective. They did. And what they found was a mouse caught in a trap that had been hidden under what-a-man Gable;s bed!
