The ambassador of a small African nation chanced to visit Russia, and was entertained by his opposite number, the Russian ambassador. For three days, the African ambassador was wined, dined, and generally treated to the best hospitality that Russia had to offer.
On the final day of his visit, the Russian ambassador said, "As your stay is coming to an end, it is time for you to play our traditional game, Russian roulette. One of the six chambers of this gun is loaded. You spin the cylinder, point the gun at your head, and pull the trigger."
