"That buzzing- noise means something. You don't get a buzzing-noise like that, just buzzing and buzzing, without its meaning something. 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. "
Winnie the Pooh and the Honey Tree (1966)
