There is a part in Winnie-the-pooh that goes like this:
C. Robin: "Now then Pooh, where's your boat?"
W.T.P.: " I ought to say" explained Pooh, "that it isn't just an ordinary sort of boat. Sometimes its a Boat, and sometimes it's more of an Accident. It all depends."
C. Robin: "Depends on what?"
W.T.P.: "On weather I'm on the top of it or underneath it."
