A joke from my cousin

Barak Obama,Sarah Pallin,and Oprah were on a plane.Barak said"If I threw 10$ out of this plane,I could make a person happy."Sarah said"If I threw 100$ out of the window,I could make 10 people happy."And Oprah said"If I threw 400$ out the window,I could make 40 people happy."And the pilot said"If I threw all you out this plane right now,I could make 40 million people happy."
