A scientist experimenting on a frog
He yells "JUMP!" at the frog and the frog jumps one metre.
Then he cuts off one of the frog's legs, yells "JUMP!" and the frog jumps half a metre.
Then he cuts off another of the frog's legs, yells "JUMP!" and the frog jumps a fifth of a metre.
Then he cuts off a third leg, yells "JUMP!" and the frog does not jump. He yells "JUMP!" again, and the frog does not jump.
"Aha!" he says. "I have my result!" So he carefully writes in his lab book: "When three legs are removed, a frog becomes deaf."

“Research! A mere excuse for idleness; it has never achieved, and will never achieve, any results of the slightest value.”
Benjamin Jowett (1817-93), British theologian
