SCENE:  It's a fine sunny day in the forest, and a rabbit is sitting
        outside his burrow, tippy-tapping on his typewriter.

        Along comes a fox, out for a walk.  

FOX:    "What are you working on?"
RABBIT: "My thesis."
FOX:    "Hmm.  What's it about?"
RABBIT: "Oh, I'm writing about how rabbits eat foxes."
        (incredulous pause) 
FOX:    "That's ridiculous!  Any fool knows that rabbits don't eat foxes."
RABBIT: "Sure they do, and I can prove it.  Come with me."

        They both disappear into the rabbit's burrow.  After a few
        minutes, the rabbit returns, alone, to his typewriter and resumes
        typing.

        Soon, a wolf comes along and stops to watch the hardworking
        rabbit.

WOLF:   "What's that you're writing?"
RABBIT: "I'm doing a thesis on how rabbits eat wolves."
        (loud guffaws)
WOLF:   "You don't expect to get such rubbish published, do you?"
RABBIT: "No problem.  Do you want to see why?"

        The rabbit and the wolf go into the burrow, and again the rabbit
        returns by himself, after a few minutes, and goes back to typing.

SCENE:  Inside the rabbit's burrow.  In one corner, there is a pile of
        fox bones.  In another corner, a pile of wolf bones.  On the other
        side of the room a huge lion is belching and picking his teeth.

        (The End)

MORAL:  It doesn't matter what you choose for a thesis subject.
        It doesn't matter what you use for data.
        What does matter is who you have for a thesis advisor.
