This is my favorite joke of all time.
Transcript of a US naval ship with Canadian authorities off the coast of Newfoundland:
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 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.”
This never really happened. Both Snopes and the US Navy have pages debunking it. But the joke is funny because it’s easy to conceive of a possible world in which it were true — everyone’s either met someone who’s tried to move an immovable object, or been that person themselves. Usually the immovable object doesn’t tell you “We’re a lighthouse, your call” quite so bluntly, which is why it’s a punchline. But it’s a form of ha ha only serious humor — true of a concept, whether or not the event actually took place.
