Barack Obama was seated next to a little girl on an airplane trip back to Washington. 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.”

The little girl, who had just opened her book, closed it slowly and said to The Obama, “What would you like to talk about?”

“Oh, I don’t know,” said the Obama. “How about What Changes I Should Make To America?” and he smiles.

“OK,” she says. “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 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?”

Obama, visibly surprised by the little girl’s intelligence, thinks about it for a second and finally says, “Hmmm, I have no idea.”

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