A KGB colonel visits a Siberian youth prison , “Why are you here?” He asked the first youth.

“For the past week my clock woke me up early so I got into work early. I’m convicted of being a spy and here I am.”

He asked the second youth the same question.

“For the past week my clock always woke me up late. I got into work late and I’m convicted of sabotage.”

He asked the third youth the same question.

“For the past week my clock always woke me up on time, so I always came to work on time.”

“And…?”

“I’ve been convicted of smuggling a clock in from the west.”
