Airplane Discussions are...er, great!

A stranger was seated next to a little girl on the Airplane when the stranger turned to the little girl and said, "Let's talk. I've heard that flights go faster 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 the deer excretes little pellets, the cow turns out a flat patty, and the horse produces clumps of dried grass. Why do you suppose that is?"

The stranger thinks about it and says, "Hmmm, I really have no idea."

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