CLEVER GAL

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?"

"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,"

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