An American battleship is lost at sea in thick fog. The first
mate reports that he can see light ahead, so the captain radios the
vessel demanding that it diverts its course to avoid a collision. A
Canadian voice responds, recommending that the battleship changes
its own course. The captain is enraged. "This is the Captain of a
US Navy ship. I say again, divert your course," he says. "No," says
the Canadian calmly, "you divert your course." The US officer is
beside himself, "This is the aircraft carrier USS Lincoln," he
explodes, "I demand that YOU change your course." There is a
moment's pause before the Canadian replies, " This is a lighthouse.
Your call."
