A stranger was seated next to Little Johnny on the

plane when the stranger turned to the boy and said,

"Let's talk. I've heard that flights will go quicker

if you strike up a conversation with your fellow

passenger."

Little Johnny, 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 Little Johnny. "That could be an interesting

topic. But let me ask you a question first. "A horse,

a cow, and a deer all eat grass. The same stuff. 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?"

"Jeez," said the stranger. "I have no idea."

"Well, then," said Little Johnny, "How is it that you

feel qualified to discuss nuclear power when you don't

know shit?"
