A stranger was seated next to little Tommy on the plane when the strangerturned to the boy and said, "Let’s talk. I’ve heard that flights will goquicker if you strike up a conversation with your fellow passenger."
Little Tommy, who had just opened his book, closed it slowly, and said tothe stranger, "What would you like to discuss?"
"Oh, I don’t know," said the stranger, "how about nuclear power?"
"Ok," said little Tommy. "That could be an interesting topic. But let meask you a question first. A horse, a cow, and a deer all eat grass; thesame stuff. Yet a deer excretes little pellets, while a cow turns out aflat patty, and a horse produces clumps of dried grass. Why do yousuppose that is?"
"Jeez," said the stranger, "I have no idea."
"Well, then," said little Tommy, "how is it that you feel qualified todiscuss nuclear power, when you don’t know shit?"
