Two men were seated next to each other on a plane when the first man turned to his seatmate and said: "Let's talk. I've heard that flights will go quicker if you strike up a conversation with your fellow passenger."
"What would you like to discuss?" the second man asked.
"Oh, I don't know," said the first man: "How about nuclear power?"
"OK," the second man replied: "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 first man: "I have no idea."
"Well, then," said the second man: "How is it that you feel qualified to discuss nuclear power when you don't know shit?"
