My Dad told it to us this afternoon and he got it from his friend in Washington.
Obama, Hillary and Mccain were flying to a debate on a plane together. To break the silence Mccain says "If I threw 5 100 dollar bills out this window, I could make five people happy." "Yes." says Obama "But I could throw out 10 50 dollar bills and make ten people happy." Then Hillary buts it "However, I could throw out 50 five dollar bills and make fifty people happy." The pilot who overheard the conversation whispers to the co-pilot "I could throw all three of them out the window and make a million people happy."
