An African leader makes an official trip to Russia. As he's leaving, the Russian leader tells him that
in Russia they have a farewell custom called 'Russian Roulette' to demonstrate one's courage.
The Russian whips out a revolver, loads one chamber, gives the cylinder a spin, puts the gun to his head and pulls the trigger.... CLICK... empty chamber. He hands the revolver to his African guest and says, "Your turn." Not to be outdone, the African repeats the ritual.. CLICK.... empty.

The next year, the Russian visits the African country. As he's leaving, the African tells him that he was very impressed with 'Russian Roulette' and that he has devised an African ritual to demonstrate one's courage. The African then disappears through a door, only to reappear a few minutes later smiling and says to the Russian, "Your turn."

The African escorts the Russian through the door. In the room are six of the most beautiful, naked women he has ever seen. The African explains that he is to choose one of the women, who will perform oral sex on him. Absolutely dumbfounded, the Russian asks, "What kind of test of courage is this?" The African calmly answers, "One of them is a cannibal."
