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 5 year old 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 ?"
"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 grass, the same stuff.
Yet a deer excretes little pellets,
while the cow turns out a flat patty,
and a horse produces clumps of dried grass.
Why do you suppose that is ?"
The stranger thinks about it and says. "Hummm, I have no idea."
Well, the little girl responded,
"Do you feel qualified to discuss nuclear power when you don't know :D:D:D:D?".
