Divert Your Course

Apparently this was an actual radio conversation: #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?"
