At the 1980 Summer Olympics in Moscow, the pole vaulting finals led to some tension between Soviet and Polish spectators. The crowd cheered on the favourite Konstantin Volkov and jeered the Polish jumper Władysław Kozakiewicz. After securing his gold medal, Kozakiewicz made an obscene gesture in reaction to the crowds taunts. After countless years of strict Soviet control, the Polish people were able to take pride in both his medal and his defiance.
In short, the Soviets got a well deserved fuck you.
