THE PARABLE OF THE SCORPION AND THE FROG

There once was a frog who lived near a creek, dividing two beautiful and bountiful fields. 

The Frog, of course, could cross the creek at will and enjoy either of the beautiful fields.  His neighbor, the scorpion, lived in only one of the fields and longed to experience the other, lovely field.

One day the frog was preparing to cross the creek, as he did frequently, when he was approached by the scorpion.  The scorpion, appearing peaceful and earnest requested "Mr. Frog may I  please ride across the creek on your back since you seem to be crossing anyhow?  You will find I do not weigh much and will not add any burden to you."

The frog quickly replied "No, for, if I let you onto my back, you will surely sting me and I will die."

The scorpion affably replied, "Well that would be a foolish thing for me to do. If I were on your back and I stung you and I would also die in the creek.   We would both perish because I cannot swim and I would surely drown.  Thus, if you were giving me a ride, I would have every reason not to sting you."

The frog thought about that for a minute, contemplating the foolishness of mutually assured destruction, and said "I see your point, Mr. Scorpion.  I am getting ready to cross now, I will stand still on the bank and you may climb on to cross."

The scorpion hopped onto the back of the frog and was peaceful there as the frog began stroking and paddling across the creek.

About halfway across the creek the body of the scorpion suddenly stiffened and its stinger protruded.  In a single, continuous motion the scorpion thrust its deadly stinger down and drove it deeply into the soft back of the frog. 

Shocked, the frog asked "why in the world would you do that now we're both going to die in the middle of this Creek!"

The frog replied quietly as he contemplated his own death "I cannot help it.  It is simply my nature."
