"The Unkindest Tut Of All"
Poor Professor MacElroy is hit on the head by a brick while at a love-in, and reverts to his other personality, King Tut. He begins publicly predicting crimes, supposedly so that the police can stop them in time, in order to gain their trust. He also tries to expose Bruce as Batman's secret identity, but is foiled by the bat-dummy and some amazing ventriloquism.

Gordon: "You don't say...you don't say? You don't say!"
Barbara: "Who was it?"
Gordon: "He didn't say."
