Giving his millions to Africa is starting to show the strain for billionaire Bill Gates. He is no longer the world's richest man. He has slipped from first place to third.
At the top for the world's richest men is Warren Buffet, second is Mexican telecom billionaire Carlos Slim .
Mr Gates has felt the pinch, he no longer wipes his behind with 100 dollar bills he has cut back to using $50 for his toilet paper.
He was spotted trying to use an expired money off coupon in the Hilton-Waldorf Towers in New York.
Soon Mr Gates will have the same retirement plan as the rest of us poor people, its called the lottery.
