In Sydney, Australia, there lived a man called Mark Simon. Mark enjoyed betting so much that he would bet on anything. One day, Mark showed a frog to a stranger. He bet the stranger $60 that the frog could jump farther and faster than any other one in Sydney. The stranger said he would bet Mark if he had a frog. Mark left his frog with the stranger and went to find a frog for the stranger. The stranger opened the frog's mouth and put a bag of sand into it Soon Mark came back with a frog for the stranger. The two frogs were put on the floor and given a push. To Mark's surprise, the stranger's frog jumped off smartly but his frog just sat there. Mark had to give $60 to the stranger. After the stranger left, Mark picked up the frog, and found it quite heavy. He turned it upside down, and the bag of sand came out He knew he had been fooled and started running after the stranger.
