A man walked into a pet shop to buy a parrot. The owner pointed to three parrots that looked identical and were perched on the same wooden bar, and said, "The one on the left is 500 yuan." The man asked, "Why is this parrot worth so much?" The owner said, "This one knows how to use a computer." Then he asked how much the one in the middle cost, and the answer he got was 1000 yuan, because besides having all the skills of the first one, this parrot also knew how to operate the UNIX operating system. Naturally, the man went on in surprise to ask the price of the third one, and the answer was 2000 yuan. He asked, "What can it do?" The owner replied, "To be honest, I've never seen it do anything; but the other two both call it the boss."
