"Radio Conversation" joke

This is the transcript of an actual radio conversation of a U.S. naval
ship with Canadian authorities off the coast of Newfoundland in October, 1995.
Radio conversation released by the Chief of Naval Operations 10-10-95.
Americans: "Please divert your course 15 degrees to the North to avoid a
collision."
Canadians: "Recommend you divert your course 15 degrees to the South to
avoid a collision."
Americans: "This is the Captain of a U.S. 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 by three destroyers,
three cruisers and numerous support vessels! I demand that you change your
course 15 degrees North, 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."
