Superstition? It keeps the elephants away
A man boards a train, and finds himself sitting in a compartment opposite another passenger who is reading The Times. Every time the other finishes a page, he tears it from the paper, rolls it into a ball and throws it from the train. Perplexed, the man asks what he is doing.
“Ah,” says the man with the newspaper. “A trick I learned in Africa. Keeps the elephants away, don’t you know.”
“But there aren’t any elephants around here!”
“Yes. Works well, doesn’t it!”
