The Soviets talked a great deal about "Druzhba Narodov," which is to say "Friendship of the Peoples," though in fact the Peoples weren't really that Friendly to each other.

So the joke, of which I was very recently reminded: What is the Friendship of the Peoples? It's when the Georgian walks hand in hand with the Armenian, and with the Ukrainian, and with the Russian, and they all go to beat up the Jew.
