Four friends go on holiday to South Africa - one English, one American, one French and one Chinese. While out trekking in the countryside they find some gold in the ground. The Frenchman, a geologist, realises that they have stumbled across a rich seam, suitable for a new mine.
The American happens to be a billionaire, so he buys the land with an arrangement that they split the profits four ways - The Englishman is an engineer, so is put in charge of extraction. The Chinese man is involved in import and export so is put in charge of supplies. The Frenchman is a manager, so is put in charge with overseeing the whole operation.
A year later the American returns to see how his investment is going. First he goes to the main office to see how the Frenchman is doing.
"Well," he says, "we're getting some gold out, but there seem to be some problems with the extraction. You'd better go down and see."
So the American walks down to the mine, meets the Englishman emerging from the entrance and asks him how things are going.
"Well" he says, "my boys are fine, but the Chinese guy just isn't pulling his weight. Go down there and you'll see what I mean."
So he walks down into the mine. After a couple of hundred yards it's almost pitch black down there and he can't see or hear anyone. All of a sudden the Chinese guy jumps out from behind a pillar and shouts "Supplies!"
