The clocks of Lies

One day, a man died and went to heaven. On getting there, he met his angel in a room full of clocks.

Man: "what are these?"
Angel: " Lie clocks. Everybody on earth have a lie clock which ticks each time the person lies"

The man noticed a golden watch that is not ticking and asked: "who owns this watch?"

Angel: "Mother Theresa. She didnt lie in her entire life time so her clock didnt tick"

Man: "ok. Where are the clocks owned by politicians?"

Angel: " Oh. There Are In our office. We use them as standing fans"
