A stranger was seated next to Little Tommy 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 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 Little Tommy. "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 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 Tommy, "How is it that you feel qualified to discuss nuclear power
when you don't know sh*t?"
