Once there was a big great white shark whose name was joey. He use to challenge everyone in the school park or anywhere. One day there came along a bull shark. Joey challenged him. He said, "Who ever is the fastest is the boss." But the bull shark said, "I don't want to be a boss." Joey said ok. They had a very big race and everyone watched them as they raced all the way. The bull shark won and everyone cheered a lot. 
Never ever say you are the best.
