A man boarded an airplane in St John's with a box of frozen crabs. The stewardess took it and promised to put it in the refrigerator.

Shortly before landing, she retrieved the crabs, but could not remember which passenger the box belonged to. So she got on the PA system and asked, "Would the gentleman who gave me the crabs in St John's please raise your hand?

Not one hand went up.

She took the crabs home.
