THE LIZARD AND THE SNAKE
A lizard happened to be looking the other way when a snake grabbed her from
behind. The snake then opened his gaping maw to swallow the lizard but the lizard
grabbed a little twig that was lying near by and blocked the snake's greedy
mouth with this clever obstacle, holding the twig turned firmly sideways between
her teeth. The snake thus failed to capture his quarry and the lizard got away.
