There is a guy selling three parrots. Another guy who wants to buy a parrot asks him, “How
much are your parrots?”

The salesman answers, “The first one is $1,000.”
“What does he know?”
“He knows 10,000 words and 500 sentences and he is able to solve mathematical
problems.”

How about the second one?
“The second parrot costs $5,000.”
“What does he know?”
“He knows 100,000 words and 10,000 sentences, is able to solve mathematical problems,
and create computer programs.”
“Then what is the price for the third one?, the buyer is wondering.”
“This one costs $20,000.”
“Really!?, wonders the buyer. What does HE know?”
“This one knows absolutely nothing, but the two others call him ‘THEIR BOSS.’”
