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?
