Actual Radio Conversation
This was a conversation between a US naval ship and Canadian authorities off the coast of Newfoundland in late 1995.

Canadians: Please divert your course 15 degrees to the south to avoid a collision.

Americans: Recommend you divert your course 15 degrees to the north to avoid a collision.

Canadians: Negative. You will have to divert your course 15 degrees to the south to avoid a collision.

Americans: This is the captain of a US Navy ship. I say again, divert YOUR course.

Canadians: No, I say again, you divert YOUR course.

Americans: This is the Aircraft Carrier USS LINCOLN, the second largest ship in the United States Atlantic Fleet. We are accompanied with three Destroyers, three Cruisers and numerous support vessels. I DEMAND that you change your course 15 degrees north. I say again, that's one-five degrees north, or counter-measures will be undertaken to ensure the safety of this ship.

Canadians: This is a lighthouse. Your call.
