Prankster

Joe liked to joke around.
He played a lot of practical jokes on people.
Most of them were really good.
But some of them backfired badly.
His best one was when he put a sign by the River Lethe.
It said “This river will help restore your memory.”
People would splash some of the water on their faces and forget everything.
Then, they’d see the sign, and splash more.
This went on for days and days.
Until his victims slowly starved to death.
There, among the bodies, was Joe.
He’d gotten wet while hammering the sign into the ground.
Dumbass.
