Charlie was a poor young boy who lived with his parents and all his grandparents. Every year his parents would buy him a wonka bar. Near his birthday Willy Wonka annouced a contest for 5 lucky people. He hid 5 golden tickets in Wonka bars and the whole world was trying to get their hands on them. Charlie's birthday came and his parents bought him a wonka bar but he didnt win. Then his grandpa wanted him to win so badly he gave him his cigarette money to buy another Wonka bar. He still didn't win. By that time there was only one ticket left. Charlie was on his way home and found money in the street, picked it up and went to the nearest store to buy a Wonka bar. Inside it was the last golden ticket! Charlie ran home and told his family but they didn't belive him. He was supposed to go to the factory and meet wonka himself. He and his grandfather went the next day with all the other winners and got to go into the Wonka factory.
