This is an actual radio conversation released by the Chief of Naval Operations, 10-10-95, MSG#H0000115020ecb52EMHS
#1: "Please divert your course 15 degrees to the north to avoid a collision."
#2: "Recommend that you change YOUR course 15 degrees to the south to avoid a collision."
#1: "This is the captain of a U.S. navy ship. I say again, divert YOUR course."
#2: "No, I say again divert YOUR course."
#1: "This is the aircraft carrier Enterprise, we are a large warship of the U.S. navy. Divert your course NOW!"
#2: "This is a lighthouse. Your call?"
No matter how many times I hear this, it always brings laughter.
