something for a long flight!
Two strangers were seated next to each other on an aircraft when the first guy turned to the second and said, "Let's talk. I've heard that flights will go much quicker if you strike up a conversation with your fellow passenger."
The second guy, who had just opened his book, closed it slowly,
took off his glasses and said to the first guy, "What would you like to discuss?"
"Oh, I don't know," said the first guy. "How about nuclear
power or international politics?"
"OK," said the second guy. "They are interesting topics. 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 guy. "I have no idea."
"Well, then," said the second guy, "How is it that you feel
qualified to discuss nuclear power or international politics when you don't know shit?"
