Two strangers are sitting in an adjacent seats in airplane. The guy
says to the woman, "Let's talk. I hear that the flight will go faster
if you strike up a conversation with your fellow passenger."
The woman, who had just opened a good book, closes it slowly, takes
off her glasses and asks, "What would you like to discuss?"
The guy says, "Oh, I don't know; how about Nuclear Power?"
The woman 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 stuff. But the deer excretes pellets;
the
cow, big patties; and the horse, clumps of dried grass. Why is that?"
The guy says, "I don't know."
The woman says, putting her glasses back on, "Oh? Well then, do you
really think you're qualified to discuss Nuclear Power when you don't

know sh*t?" :laugh:
