Once there was a parrot on sale in a pet
store. It was a beautiful red and blue bird. It sat on a perch 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 pet store
owner, "But why is it so expensive? Is it unsual 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 pet store owner
asked him, "Do you see those string 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 pet store 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 wold happen if I pulled both
strings at the same time?"
"I'll fall off
my perch, you fool!" the parrot said.
