Duttons plan to go Nuclear, page-3

Not humour.
Wrong forum.
But valid point.

Speaking of boats - an oldie but a goodie:

Captain of the USS John C. Stennis navigating in a fog, sees a light in the seas ahead:

He turns on his signal lamp and sends, “Change your course, 10 degrees west.”

The light signals back, “Change yours, 10 degrees east.”

The captain gets a little annoyed. He signals, “I’m a US Navy captain. You must change your course, sir.”

The light signals back, “I’m a Seaman First Class. You must change your course, sir.”

Now the captain is mad. He signals, “I’m an aircraft carrier. I’m not changing my course.”

The light signals back a final message: “I’m a lighthouse. Your call.”
