There was a long drought in Central Africa. The witch doctor had tried all his rainmaking dances, invocations and imprecations, but to no avail.

One of the elders observed that rain was never a problem in England, so why not send the witch doctor to London to learn the secret?

Off the witch doctor went to England. Two weeks later, on his return, the tribe gathered, agog to hear his new-found wisdom.

"Well," he said, "these crazy men had a big paddock of grass enclosed by a white picket fence. In the middle were two sets of small sticks driven into the ground. Two men, each with a club, stood next to these sticks and waited for a lot of other men to spread themselves all over the paddock. Then two more men, wearing black trousers, long white coats, four sweaters and six hats, came out to keep a close watch on the men with the clubs. Then one man got a red rock and threw it at one of the fellers with a club. AND DOWN CAME THE RAIN!"

It might be old but I never heard it before, very good although I did see it coming!
