One day a scorpion and a lion were stranded on an island surrounded by flood water. The scorpion knew the lion could swim, and he asked if he would take him across the flooded river on his back. The lion at first refused and said, ‘I will not, because you will sting me.’
“The scorpion replied, ‘It would be foolish for me to sting you because then we would both drown.’
“The lion saw the logic in the scorpion’s words, and agreed to carry the scorpion across. But when they were halfway across the river the scorpion stung the lion. The stunned lion asked, ‘Why did you sting me? Now we will both die!’
“The scorpion replied, ‘Because I’m a scorpion … and that’s what scorpions do.”
