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?”
“$2,000,” the assistant replies.
The man is shocked and asks the assistant why it’s so expensive.
“This parrot is a very special one,” the assistant explains.
“He knows typewriting and can type really fast.”
“What about the green one?” the man asks.
“He costs $5,000,” the assistant says.
“He knows typewriting and can answer incoming telephone calls and takes notes.”
“What about the red one?” the man asks.
“That one’s $10,000.”
“What does HE do?” the man asks.
“I don’t know,” the assistant admits, “but the other two call him ‘boss.'”
