A blazing fire was roaring through the forest and the animals gathered at the shore of the lake in order to swim to safety. Unable to swim, a scorpion attempted to convince a tortoise why he should give him a ride on his back. Unconvinced, the tortoise replied, "You are my natural enemy, how can I trust that you will not sting me while we are in the water?" "That would be foolish!" replied the scorpion, "For then we would both die – trust me, I won't sting you!" So the tortoise allowed the scorpion to climb on board, but half way across he savagely stung his rescuer at the base of his neck. As both animals sank to certain death the tortoise cried out in despair, "Why did you do that?" to which the scorpion replied, "Because it's in my nature to sting!"
