Three men sit in a jail in Dzerzhinsky Square. The first asks the second why he has been imprisoned, and he says, 'Because I criticized Karl Radek.' The first man responds, 'But I am here because I spoke out in favor of Radek!' They turn to the third man who has been sitting quietly in the back, and ask him why he is in jail too.

Get ready for the punchline that's out of this world!
