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 the farce of global warming or joke called 'Obamacare'," and he smiles smugly.
"OK," she said. "Those could be interesting topics. 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 esteemed legislator, visibly surprised by how sharp the girl is, thinks about it and says, "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 sh*t?"
