This is an excerpt from the transcripts of an actual radio conversation between a US naval ship and Canadian authorities off the coast of Newfoundland in October 1995.

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 US Navy ship. I say again, divert YOUR
           course.
Canadians: No, I say again divert YOUR course.
Americans: THIS IS THE AIRCRAFT CARRIER USS MISSOURI, WE ARE A LARGE WARSHIP
           OF THE US NAVY. DIVERT YOUR COURSE NOW.
Canadians: This is a lighthouse.  Your call.
