A stranger was seated next to a little girl on the airplane when the stranger
turned to her and said, 'Let's talk. I've heard that flights go quicker if you
strike up a conversation with your fellow passenger.'


The little girl, who had just opened her book, closed it slowly and said to the
stranger, 'What would you like to talk about?'


'Oh, I don't know,' said the stranger. 'How about nuclear power?' and he
smiles.


'OK, ' she said. 'That could be an interesting topic. But let me ask you a
question first. A horse, a cow, and a deer all eat the same stuff - grass - .
Yet a deer excretes little pellets, while a cow turns out a flat patty, and a
horse produces clumps of dried grass. Why do you suppose that is?'


The stranger, visibly surprised by the little girl's intelligence, thinks about
it and says, 'Hmmm, I have no idea.'


To which the little girl replies, 'Do you really feel qualified to discuss
nuclear power when you don't know shit?
