Once there was a boy called Jack who lived with his mother. They were poor and they had to sell their cow. On his way to market he met a stranger who gave him five magic beans for the cow. His mother was mad and threw them out of the window. They started to grow. Jack climbed them and saw a castle. He knocked and the giantess told him to hide from her hungry husband. The giant ate a lot of food and ten started counting his coins but soon he was snoozing. Jack snatched the golf and raced down the beanstalk.
