Warren Buffett has shown us once again why he consistently tops the list of the most philanthropic billionaires. On Friday, the Berkshire Hathaway CEO gave $2.2 million to the charity Girls Inc. of Omaha, Nebraska, after winning a 10-year bet that hedge fund managers couldn't beat the stock market average, reports the Omaha World-Herald.

Roberta Wilhelm, the charity's executive director, says the proceeds will go toward a transitional housing program for young women who are too old to remain in foster care.
