Two strangers are sitting in adjacent seats in an airplane. One man says to the other, "Let's talk. I hear that time will pass faster if you strike up a conversation with your fellow passenger."
The other passenger, who had just opened a book, closed it slowly, took off his glasses and asked, "What would you like to discuss?"
The first man answers, "Oh, I don't know. How about nuclear power?"
The other man says, "OK, that could make for some pretty interesting conversation. But let me ask you a question first: A horse, a cow, and a deer all eat the same type of food, but the deer excretes pellets, the cow excretes big patties, and the horse clumps of dried grass. Why is that?"
The first man answered, "I don't know."
The second man said, "Oh? Well then, do you really think you're qualified to discuss nuclear power when you don't know shit?!"
