Stalin, Krushchev and Brezhnev are riding on a train when it suddenly stops. Stalin says “Comrades we must execute the driver to motivate the others”. The poor driver is dragged out into the snow and shot. the train still doesn’t move. Krushchev says “Comrades, we have made a dreadful error. We must set this thing straight and rehabilitate the poor driver.” So the driver is posthumously rehabilitated. Still the train doesn’t move. “Listen”, says Brezhnev, “The solution is obvious. Let’s pull down the curtains, bounce up and down on the seats and pretend the train is moving”.
