This is a Soviet joke...
Two friends, Yuri and Mikhail, are feeling rather weird. Yuri says that he will give Mikhail 5,000 roubles if he stands in Red Square, and at high noon, shouts at the top of his lungs, "Brezhniev is an idiot!" Mikhail figures that he'll get a couple weeks in jail for hooliganism, at which point he'll be able to enjoy the money. So, he does the deed. Of course, he is arrested by the KGB. The agent says, "20 years for you."
"But I thought the penalty for hooliganism was two weeks!"
"We're not arresting you for hooliganism, we're arresting you for revealing state secrets."
