This happened in Australia during a waterpolo game.It was the end of the game and the players moved very slowly.Suddenly one of the players jumped out of the water saying that one of the forwards of the opposite team bit him in the leg under water.The forward called out of the water but he refused to admit it.In some minutes another player jumped out of the water and cried:"If you don't stop the game I shall not go back into the pool."The water was let out of the pool and the players found a letter in their dressing-room that read:"I have been a water-polo fan for many years.Today's game is very slow ,so I decided to make the players move faster.I hope that my little crocodile will do it better."
