Frog and the scorpion
A scorpion asks a frog to carry it across the river. The frog hesitates, afraid of being stung.
“But” the scorpion argues, “if I sting you, we will both drown”.
“Right”, said the frog, and agrees to carry the scorpion.
They wade into the river. Midway across, the scorpion stings the frog.
With his dying breath, the frog says, “What did you do that for? Now we both will die!”
The scorpion shrugs. “It's in my nature”.
