The fax and the turtle

For want of a better meal, a starving fox captured a turtle, but then could not manage to break through the solid shell in order to eat it. "You should try putting me in the water for a while to soften me up." suggested the shrewd turtle.

This sounded like excellent advice to the fox. He carried his prey to the stream and immersed it in the current. The turtle, who was a superb swimmer, slid out of the fox's paws and re-emerged in mid stream laughing. There are animals who are even more cunning than you. Now you'll stay hungry!"
