At a concentration camp in Siberia, three inmates are talking with each other about why they are in the camp. One says: “I’m here for saying that Karl Radek was a counter-revolutionary.” The second says: “Isn’t that interesting? I’m here for saying that he was not a counter-revolutionary.” They turn to the third man and ask: “What are you here for?” He answers: “I’m Karl Radek.”
