Your post's title reminds me of this Exchange:
This is the transcript of a radio conversation of a US 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 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 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 countermeasures will be undertaken to ensure the safety of this ship.Canadians: This is a
lighthouse. Your call.

In this instance, Dr. Smith is the Lighthousekeeper...
