It's Soviet Russia, 1978, and Rabinovich is woken up by a knock on the door. Rabinovich: "Who's there?" A firm voice responds: "Post office. Please open." Rabinovich opens the door and is unsurprised to find Two KGB agents standing there. One of them is holding an envelope. KGB officer 1: "Tell us, Comrade Rabinovich, what is the best government system in the world?" Rabinovich: "Why, Communism." KGB officer 2: "And what country has the best living standards?" Rabinovich: "The Soviet Union, of course." Officer 1: "And what constitution is the best at protecting the rights of the citizens?" Rabinovich: "The Soviet Constitution, Comrades." Officer 2: "Then do you mind explaining to us, Comrade Rabinovich, why you have recently filed a request to emigrate to France?" Rabinovich: "Well, I heard that over there, they don't deliver the mail in the middle of the night."
