A sea cadet is being examined: “Suppose you’re at sea and a storm comes up, what would you do?”
Cadet: I’d throw out an anchor.
Examiner: And what if another storm comes up.
Cadet: I’d throw out another anchor.
Examiner: But what if an even bigger storm comes up?
Cadet: I throw out an even bigger anchor.
Examiner: But where are you getting all your anchors from?
Cadet: The same place you’re getting your storms.
