LITTLE GIRL ON A
PLANE

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?
