Jim went into a pet shop to buy a parrot. An assistant asked which one he wanted. “How about the yellow one?”

“He’s £2000.”

Jim was shocked and asked why it was so expensive.

”The parrot is very special. He types really quickly.”

”What about the green one?”

”He costs £5000 because he can type, answers incoming telephone calls and takes notes.”

”The red one?” Jim asked desperately.

“He costs £10,000.”

”What does HE do?”

”I don’t know. But the other two call him boss.”
