A Smart Blonde

A guy boarded a plane and found himself seated next to a cute blonde. He immediately turned to her and made his move. "You know," he says, "I've heard that flights will go quicker if you strike up a conversation with your fellow passenger. So let's talk."

The blonde, who had just opened her book, closed it slowly and said to the guy, "What would you like to discuss?"

"Oh, I don't know," said the guy. "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 the same stuff, grass. Yet the deer excretes little pellets, the cow turns out a flat patty, and the horse produces muffins of dried poop. Why do you suppose that is?"

The guy was dumbfounded. Finally he replied, "I haven't the slightest idea."

"So tell me," said the blonde, "How is it that you feel qualified to discuss nuclear power when you don't know sh!t?"
