Three men are serving jail time in East Germany. As they wait for time to pass, they eventually talk about why they were imprisoned. The first one says: "Everyday, I got to work five minutes early, so they condemned me for espionage!" The other two ask the second man. He says: "Everyday, I got to work 5 minutes late, so they condemned me for sabotage!" Men number one and two are getting curious about the third man. Upon asking him, he says: "Everyday, i got to work exactly in time, so they condemned me for using a watch from West Germany!"
