A man dies and goes to heaven. In heaven, he sees a wall of very large clocks.
He asks the Angel, “What are all these clocks for?”
Angel answers, “These are lie clocks, every person has one lie clock. Whenever you lie on earth, the clock ticks once.”
The man points towards a clock and asks, “Who’s clock does this belong to?”
Angel answers, “This clock belongs to Mother Teresa. It has never moved, so she has never told a lie.”
Then the man asks, “Where is those politicians’ clock?”
The Angel replies, “Those are in our office, we use them as table fans.”
