A stranger was seated next to little Tommy on the plane when the stranger turned to the little boy and said "Let's talk. I heard that flights will go quicker if you strike up a conversation with your fellow passengers." Little Tommy, who had just opened his book, closed it slowly and said to the stranger "What would you like to discuss?" "Oh, I don't know," said the stranger. "how about nuclear power?"

"OK," said Tommy. "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 the deer excretes little pellets, while the cow turns out a flat patty, and a horse produces clumps of dried grass. why do you suppose that is ?. " "jeez," said the stranger. "I have no idea." "Well then, " said little Tommy,"How is it that you feel qualified to discuss nuclear power when you don't know Shit?"
