The Rabbit's Thesis

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.

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.
