  A man was sitting in the park watching the ducks on the pond, when a

woman went to him. She had a white dog. She sat down on a bench, took out a

magazine and began to read. The dog was sitting between her and the man. After

it had been sitting quietly for about ten minutes, the dog turned and looked up at

the man.

  "Excuse me,"the dog said, "but you look like a kind man. Please buy me

from this terrible woman."

  The man could hardly believe his ears. A dog spoke to him in English!

  "She is so mean to me, " the dog continued, "She never pets me or plays

with me. She doesn't feed me properly and she often beats me when she's in a

bad mood, which is most of the time.”

  The man was amazed to hear the dog say all this. He was even more

surprised when the dog added, "And I'm really a very good dog. I'm quite

famous, too. I won a medal in the last war and was twice wounded in action. I've

saved three children- two from drowning and one from a fire."

  The man decided that he would try to buy the dog from the woman. He

would pay a lot of money if necessary. The dog would soon earn tens of

thousands of dollars on television. It could be the world’s first talking dog.

  Excuse me,"he said to the woman, "but I love your little dog. Will you sell

him to me? "

  I'll be glad to sell him," the woman said. "You can have him for ten

dollars."

  "Ten dollars!” the man said. "Only ten dollars? Why so little?" "Because, "

the woman said, "he always tells lies."
