Frog and the scorpion

A one-scene play.

A scorpion asks a frog to carry it across the river. The frog hesitates, afraid of being stung.
“But,” says the scorpion, “if I sting you, we will both drown”.
“I see!” says the frog. “Hop on!”
They wade into the river. Midway across, the scorpion stings the frog.
With his dying breath, the frog cries, “Why did you do that? Now we both will die!”
The scorpion shrugs. “It’s in my nature.”

The rest is silence.
