A guy was seated next to a 10-year-old girl on an airplane. Being bored,
he turned to the girl and said,
"Let's talk. I've heard that flights go quicker if you strike
up a conversation
with your fellow passenger."
The girl, who was reading a book, closed it slowly and said to the guy,
"What would you like to talk about?"
Oh, I don't know," said the guy. "How about nuclear power?"
"OK," she said. "That could be an interesting topic. But let me ask you
a question first. A horse, a cow and a deer all eat the same stuff... grass.
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?"
The guy thought about it and said, "Hmmm, I have no idea."
To which the girl replied, "Do you really feel qualified to discuss
nuclear power when you don't know shit?"
