A US Congressman was seated next to a little girl on the airplane leaving from Washington, DC, when he 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."Thanks to Wand.
The little girl, who had just opened her book, closed it slowly and said to the total stranger, "What would you like to talk about?"
"Oh, I don't know," said the congressman. "How about global warming or universal health care?", and he smiled smugly.
"OK," she said. "Those could be interesting topics. But let me ask you a question first. A horse, a cow, and a sheep all eat the same stuff - grass. Yet a sheep 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 legislator, visibly surprised by the little girl's intelligence, thinks about it and said, "Hmmm, I have no idea."
To which the little girl replies, "Do you really feel qualified to discuss global warming or universal health care when you don't know shit?"
