Amy had three sons, Dave, Bill and Bob. Every year her sons sent her expensive gifts on her birthday. The eldest son Dave had a lot of money and he wanted his mother to have the most expensive gifts, but he didn't know what to buy. So he put an ad   in the newspaper. " Wanted ---- the greatest gift for my mother." About a week before his mother's birthday, a man came to his office. He brought a big bird. This bird can speak six languages and sing eight songs," the man said." ".Really? I'd like to listen to it, " Dave said. The man made the bird talk in French and tell a joke in Japanese. Then the bird sang a beautiful song. Dave was very happy and paid eight thousands dollars for the bird. The next day Dave sent the bird his mother with a birthday card. The day after his mother's birthday he called his mother, " Well, mother," he asked, " What do you think of the bird?" " Oh, it's very delicious, dear," said his mother. How many songs could the bird sing?
