A man goes into heaven...

...he sees a lot of clock's and asks what they're for.

Jesus says, "These are lying clocks. If a person tells a lie the minute hand moves."

Jesus points to one clock and says, "This is Abraham Lincoln's clock, the hands have only moved a bit."

Jesus points to another clock and says, "This is my Mother's clock, it has never moved since she has never told a lie."

Suddenly the man asks where George Bush has his clock.

Jesus says, "It used to be in my office for a fan."

The man asks why it's not his fan anymore.

Jesus answers, "We're using Obama's for a generator to get the Air Conditioning going."
