The African ambassador was impressed with the courageous game, and thought hard about the subject before the Russian Ambassador was due to visit his country the next year.

When the visit came, the African ambassador treated the Russian with all hospitality, until the final day of his stay. Leading him to a private room in the palace, the African ambassador spoke, "Now, time for you to sample our game, African roulette". He then led the Russian into the room, the only occupants of which were six stunning and naked women.
The African ambassador said, "These women are the most beautiful members of one of our tribes. Any one of them will give you a oral sex - take your pick".
The Russian was not entirely averse to this idea, but he couldn't see the connection with Russian Roulette. He said, "Well, ok, great, but where's the roulette part? Where's the danger?"

With a big grin on his face, the African ambassador answered:
"One of them is a cannibal."
