“In the days of the Roman Colosseum, captured soldiers were regularly thrown to the lions. But one soldier earned a reputation for bravery and managed to save his life by a bold act. When a lion sprang toward him with lunch on its mind, the man whispered something in the lion’s ear just at the last moment. The lion cowered, turned a sickly green, and then slunk back into its cage. This happened again and again, with even the empire’s fiercest lions turning tail once they had heard what the man whispered. The emperor, curious to understand the man’s power over these beasts, promised him his life in exchange for the secret of how he caused the lions to leave him alone. “It’s simple,” the soldier told the emperor. “When a lion is about to attack, I just whisper, ‘After you’ve eaten, they’re going to ask you to make a short speech.’ Works every time.”
