Pres visits an elementary school & a girl asks him "a deer excretes little pellets, while a cow turns out a flat patty, and a horse produces clumps of dried grass. Why do u suppose that is?" Obama, visibly surprised with question, thinks about it for a second and finally says, "Hmm, I have no idea." To which the little girl replies, "Do you really feel qualified to change America when you don't know s**t?"
