Once there lived a man who had a parrot. The man tried to teach the parrot to speak. But

the parrot could learn only the phrase, “There is no doubt about it.” (в этом нет

сомнения). The parrot always said these words and always gave the same answer.

“There is no doubt about it”.

At last the man decided to sell (продавать; sold) the parrot. He went to the street and

began to cry, “Twenty dollars for a very clever parrot!”

One woman heard this. She came up to the parrot and asked, “ Are you worth twenty

dollars?” The parrot answered, “There is no doubt about it”.

“What a clever parrot”, she said and bought the bird.
