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.
