Khrushchev is a pig

 A man is brought before a judge, accused of shouting "Khrushchev is a pig!" in Red Square for all to hear.

There's plenty of evidence and multiple eyewitnesses, so the man is swiftly sentenced to twenty-five years in prison.

"Twenty-five years?!" he shouts. "I thought insulting the General Secretary was only five years!"

"It is," the judge replies. "The other twenty are for revealing state secrets."

One popular variant after Khrushchev's reign changes the offending slogan to "Brezhnev is an idiot." Another has the prisoner be paroled after the leader makes a prominent state visit because it's now public knowledge.
