RAY: An off-duty policeman is working as a night watchman in an office building. He's doing his rounds and he comes upon a closed door. Behind the door he hears voices; people are talking and an argument seems to be taking place. He hears someone say, "No, Frank, no; don't do it, you'll regret it." Bang! Bang! Bang!
The night watchman bursts through the door; what does he see? A dead man on the floor. And the proverbial what? Smoking gun.
And in the room, are three living people; a minister, a doctor, and a plumber. He walks over to the minister and says, "You're under arrest. You have the right to remain silent."
How does he know that it was the minister that pulled the trigger?
RAY: Here's the answer. Only one of them could have been named Frank, because the other two, the plumber and the doctor, were women.
