The difference between smart and stupid is not always apparent
THERE'S this story I remember about a lighthouse keeper who went downstairs on a beautiful cloudless summer day to answer a knock on the door.
"Terribly sorry to disturb you, old boy," said the middle-aged tanned gentleman at the door. "My wife and I were sailing by and saw this lighthouse, and came in for a closer look, and we've run aground. Can you help us?"
"Sir," said the lighthouse keeper, "do you know what this is?"
"Well of course old chap. It's a lighthouse."
