A travelling salesman was opening up new territories in Africa. One day he fell ill.
Being a man of action, he sought immediate medical attention. Even though the only nearby facility was a witch doctor, he went to see the man.
The witch doctor looked him over, then cut a long, thin strip from a leather hide and gave it to the salesman, saying “Chew on this and by the time it’s all gone, you’ll feel better.”
As mentioned, the salesman was a man of action, so he spent the rest of the day chewing on the piece of leather. Nonetheless, he didn’t feel better, in fact, he felt worse.
So he went back to the witch doctor and said, “Doctor, the thong is ended, but the malady lingers on!”
