A man on a street corner in Moscow spends all day yelling: “The president is an idiot!”

After a while, the police arrive and arrest him. “It’s illegal to insult President Putin,” the police sergeant says.

The man protests. “You don’t understand, I was talking about the Ukrainian president. He’s the one I was insulting.”

The sergeant fixes him with a stern look. “You don’t fool us, everyone knows who the idiot is.”
