Question: When a cop was going through a restaurant, he heard someone yell, "No John, not the gun!" He dashed inside, where he discovered a doctor, a lawyer, a priest, and a dead corpse on the floor. He quickly approached the man and arrested him. He was not present when the shooting occurred, there was no obvious evidence to indicate who shot the guy, and no one notified him who the killer was. How did the cop recognize the milan so quickly?

Answer: The milan was the only male. The doctor and lawyer were females, so the cop knew that "John" was the milan.
