A man was seated next to a boy in an airplane. He was feeling bored so he turns to the boy and says, Lets talk.
The boy, surprised, asks "What do we talk about?"
Man replies, how about the nuclear power?
Confused, the boy says, before that let me me ask you a question...
The boy continues, "Horse, Cow and Deer, all eat the same grass. Yet deer excretes pellets, cow flat potty and horse clumps. Why?"
Surprise over boy's knowledge, the man simply says "I don't know".
The boy asks, "Do you really feel enough qualified to discuss nuclear issues when you don't even know shit?"
Moral: Don't judge a person by appearance. Some times, even kids might be more knowledgable than adults
