So there is a story about a discussion that took place in the fog. This version is written by Tom Wadsworth posted on DASMA in 2005.
Plowing at night through rough, foggy seas, a battleship’s radar suddenly indicates an object directly in its path. The ship’s captain sends a radio signal, “We are on a collision course. Advise you to change course 10 degrees north.”
A response crackles over the radio: “Negative. We advise you to change course 10 degrees south.”
The captain can now see a blinking light from the approaching object. Perturbed, he bellows a reply: “I’m a ship’s captain. Change course 10 degrees north, now!”
“I’m a seaman second class,” comes the reply. “Advise that you change course 10 degrees south to avoid imminent collision.”
The captain is furious. He blurts another command: “This is a battleship! Change your course immediately!”
Back comes the calm reply: “This is a lighthouse.”
The battleship changed course.
Let’s get into this message and see if there is a correlation.
