The parable goes something like this: A frog and a scorpion sit at the edge of a fast-flowing stream. The scorpion wants to get across. Asks the frog for a lift. The frog replies, "You're a scorpion. You'll sting me while you're on my back."
"If I do that," the scorpion replies, "we will both drown, so obviously I won't do that." The frog is persuaded by the logic of this. Halfway across the steam, however, the frog feels the unmistakable pinch of a stinger on his back. As the paralysis sets in and he starts to sink, he croaks out:
"Why would you kill us both?" The scorpion's last reply, as the water washes over his mandibles (OK, there's a little artistic license going on here, not least of which is the talking amphibians and insects):
"I couldn't help it! This is who I am!"

"set new land speed records for depreciation" that quote's worth the price of admission 😉
BTW, there's another common version of the frog/scorp parable. A lady finds a half frozen Viper (not Chrysler-related) and feeling pity for one of God's wonderful creatures, brings it into her warm home. It thaws out, bites her, she asks why as she lays dying, it tells her, "you knew what I was when you took me home". Jack, you & I can never let our ex's get together, period. Something about not crossing the streams.
