How much do you know....

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?"
