A 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?"
"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 a 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, "Hmmm, I have no idea."
"Do you feel qualified to discuss nuclear power when you don't know
shit?"
