What does matter is who you have for a thesis advisor.

Finally, the camera pans into the rabbit's cave and, as everybodyshould have guessed by now, we see a mean-looking, huge lion sittingnext to some bloody and furry remnants of the wolf and the fox.

“Oh, he’s my advisor,” said the rabbit, at which time the lion pounced and ate the fox.

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 eat 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.

-- What does matter is whoyou have for a thesis advisor.

And the moral is thatyour thesis topic really  matter - as long as you have the rightthesis advisor.

Reluctantly, the fox agreed, and he followed the rabbit down into the hole. There, in the rabbit’s hole, the fox saw a pile of bones in one corner, and a lion typing on a laptop in the other.
