A US Congressman was seated next to a little girl on the airplane when the Congressman 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 the banking crisis?” and he smiles.

“OK,” she said. “That could be an interesting and timely topic. But let me ask you a question first. A horse, a cow, and a deer all eat the same stuff – grass. 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 Congressman, visibly surprised by the little girl’s intelligence, thinks about it and says, “Hmmm, I have no idea.”

To which the little girl replies, “Do you really feel qualified to discuss banking when you don’t know shit?”
