In the middle of foggy night in the NW Atlantic....

two lights are heading directly for one another...

and on the radio an American voice is heard saying "we suggest you alter course by 10 degrees".

Back comes the reply from a wee kilted Scot, "Nay!"

Then the American voice says "this is the battleship USS Missouri leading the American Atlantic battle fleet, you had better alter course by 10 degrees."

Back comes the reply

"och weel, this is the Hebrides lighthoose... but it's yar call, Jimmy"
