In a forest a fox bumps into a little rabbit, and says, "Hi, junior, what
are you up to?"
"I'm writing a dissertation on how rabbits eat foxes," said the rabbit.
"Come now, friend rabbit, you know that's impossible!"
"Well, follow me and I'll show you."
They both go into the rabbit's dwelling and after a while the rabbit emerges
with a satisfied expression on his face.
Along comes a wolf. "Hello, what are we doing these days?"
"I'm writing the second chapter of my thesis, on how rabbits devour wolves."
"Are you crazy? Where is your academic honesty?"
"Come with me and I'll show you." ......
As before, the rabbit comes out with a satisfied look on his face
and this time he has a diploma in his paw.
The camera pans back and into the rabbit's cave and, as everybody should
have guessed by now, we see an enourmous mean-looking lion sitting next
to the bloody and furry remains of the wolf and the fox.
The moral of this story is:
It's not the contents of your thesis that are important --
it's your PhD advisor that counts.
