Winnie-the-Pooh sat down at the foot of the tree, put his head between his paws and began to think.
“If there’s a buzzing-noise, somebody’s making a buzzing-noise, and the only reason for making a buzzing-noise that I know of is because you’re a bee.”
Then he thought another long time, and said: “And the only reason for being a bee that I know of is making honey.”
And then he got up, and said: “And the only reason for making honey is so I can eat it.” So he began to climb the tree.
