Once there was a parrot on sale in a pet store. It was a beautiful red and blue bird. It sat on a perch ( 横杆 ) in the middle of the store, so that everyone could see it when they came in. The owner was very proud of it and asked a high price for it.  

One day a man went into the store. “ That’s a beautiful bird,” he said to the owner, “ But why is it so expensive? Is it an unusual bird?”

“ No, it’s not very unusual. It’s expensive because it can talk.” the pet store owner said.

“ I see. How can I make it talk?” the man asked.

The owner asked him, “ Do you see those strings ( 细绳 ) tied to each of the bird’s legs?

“ Yes,” the man answered.

“ Well, you pull those strings,” the pet store owner told him. That will make the parrot talk.”

The man asked, “ Do you mind if I try?”

“ Not at all,” the owner said.

The man walked up to the parrot and pulled the string on its left leg. The parrot said, “ Good morning.”

The man pulled the string on the parrot’s right leg. This time the parrot said, “ How are you today?”

“ That’s not very interesting,” said the man. “ Any parrot could do that.” Then he laughed, “ But what would happen if I pulled both strings at the same time?”

“ I’ll fall off my perch, you fool !”the parrot said.
