On his last day, the Russian foreign minister took the African foreign minister into a room with a table on which lay a revolver. "My comrade, since you are about to leave, I must introduce you to a custom we have here in Russia, something called RUSSIAN ROULETTE. It is a true test of manhood and worth, and how it works is that you must take the revolver, spin the cylinders, hold the revolver to your head and then pull the trigger. Only one of the six chambers is loaded."
The African leader, being of proud warrior stock and a courageous man, took the revolver, spun the cylinder, snapped it shut, pointed it at his head and sighed with relief when all he heard was 'click', but no shot.
Well impressed with his bravery, he and the Russian drank vodka until the African leader had to be carried aboard his plane.
Six months later the Russian foreign minister visits the African foreign minister's
country. The African, remembering keenly the Russian roulette he had to play previously, took the Russian into a room on the last day of his visit. In the room were six beautiful, naked young women.
"To prove your courage and manhood, see before you six of the most beautiful women from each of our tribes. This is something I call 'African roulette'. You may pick any one of them and they will give you a blowjob."
The Russian, not too averse to this idea at all, asks the African, "But where is the risk? To be called roulette there must be some form of risk involved."
The African smiles broadly and says "One of the six is a cannibal."
