OMG - what a friggin laugh

The terrible trio have escaped the prison vortex of Monk's dismal Political (soapies) Forum, like it was a bad smell.
They've rushed here to the green pastures of this Forum and immediately continued on where they left off before being banned.

The three Scorpions approached the stream's edge. There they asked a Frog, sitting on an Indian log nearby.
"Could you please allow us to crawl upon your back so that you may safely take us to the other side?"
The Frog responded
"Why do you wish to voyage across to the other side - what's wrong with the one you are on?"
The three Scorpions in unison answered
"Because this side is an empty place and we are going hungry and will die, if we stay."
The Frog thought a bit, leaped into the stream waters and frog-stroked up to the edge where the Scorpions were waiting, half-accepting - but cautiously he asked
"If I allow you to jump on my back for me to take you across the water - you three will sting me!"
"Oh no - we promise. Why would we sting you to die? That would most certainly mean we would drown to death. How ever could we reach the other side, if we did that? We will not sting you!"
they promised.
Convinced, the Frog touched the edge and allowed the three Scorpions to crawl onto his back. He began to reach the halfway mark of the stream and suddenly he felt a terrible pain in three points of his back. In agony he shouted at the three Scorpions
"Why did thou sting me in the back, when thee promised not to? Now surely I will die and you will all die too by drowning!"
The three scorpions just said in unison
"It's our nature."
