One of my favorite quotes from Babylon 5:
Delenn: This is Ambassador Delenn of the Minbari. Babylon 5 is under our protection. Withdraw or be destroyed!
Earth Force Officer: Negative! We have authority here. Do not force us to engage your ship.
Delenn: Why not? Only one human captain has ever survived battle with a Minbari Fleet. He is behind me. You are in front of me. If you value your lives, be somewhere else!
