Scene: It'a 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 of
walk.

Fox: "What are you working on?"
Rabbit: "My thesis."
Fox: "Hmm. What is it about?"
Rabbit: "Oh, I'm writing about how rabbit eat foxes."
(incredulous pause)

Fox: "That's ridiculous! Any fool know that rabbits don't eat foxes!"
Rabbit: "Come with me and I'll show you!"

They both disappear into the rabbit's burrow. After a few minutes,
gnawing on a fox bone, the rabbit returns to his typewriter and resumes
typing. Soon a wolf comes along and stops to watch the hardworking rabbit.

Wolf: " What's that you are writing?"
Rabbit: " I'm doing a thesis on how rabbits eats 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.
Finally a bear comes along and asks, "What are you doing?

Rabbit: " I'm doing a thesis on how rabbits eats bears."
Bear: "Well that's absurd!
Rabbit: "Come into my home and I'll show you"

As they enter the burrow, the rabbit introduces the bear to the lion.

Moral:
IT DOESN'T MATTER HOW SILLY YOUR THESIS TOPIC IS
WHAT MATTERS IS WHO YOU HAVE FOR A THESIS ADVISOR.
