A man dies and goes to heaven. In front of him was a large wall with clocks, each with a little name on it.
“What are those?” he asked G-d.
“Well, each time someone tells a lie, their clock moves a little bit.”
One was stopped- “That was was Washington’s, the first president of the USA. He almost never lied.”
“So where is Obama’s, our next president?”
“Oh, that one is in my office. I use it as a ceiling fan.”
