I'm reminded of this joke:
US Ship: "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."
US Ship: "This is the captain of a US Navy ship. I say again, divert YOUR course."
Canadians: "No, I say again, you divert YOUR course."
US Ship: "THIS IS THE AIRCRAFT CARRIER USS ABRAHAM 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."
