One day a man goes to a pet shop to buy a parrot. The assistant takes the man to the parrot section and asks the man to choose one. The man asks, 'How much is the yellow one?'
The assistant says, '$2000.' The man is shocked and asks the assistant why it's so expensive. The assistant explains, 'This parrot is a very special one. He knows typewriting and can type really fast.'
'What about the green one?' the man asks.
The assistant says, 'He costs $5000 because he knows typewriting and can answer incoming telephone calls and takes notes.'
'What about the red one?' the man asks.
The assistant says, 'That one's $10,000.'
The man says, 'What does HE do?'
The assistant says, 'I don't know, but the other two call him boss.'
