Smart Blonde

Two strangers were seated next to each other on the plane when the first guy turned to a beautiful blonde and made his move by saying, "Let's talk. I've heard that flights will go quicker if you strike up a conversation with your fellow passenger."

The blonde, who had just opened her book, closed it slowly, and said to the first guy, "What would you like to discuss?" "Oh, I don't know," said the player. "How about nuclear power?"

"OK," said the blonde. "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?"

"Oh brother," said the guy. "I have no idea."
"Well, then," said the blonde, "How is it that you feel qualified to discuss
nuclear power when you don't know shit?"
