A math professor at DePaul once figured out that the odds of picking every game correctly in the NCAA March Madness bracket is 1 in 128 billion, notes Yahoo Sports. (And that assumes basketball knowledge.) If those odds aren't too daunting, then Warren Buffett has just the contest for you: He's offering $1 billion for a perfect bracket this year, reports Bloomberg. Technically, his Berkshire Hathaway is backing a contest offered by Quicken Loans as a publicity stunt, but the money is the same. Get all the games right, and choose between 40 annual installments of $25 million or a lump sum of $500 million. (More strange stuff stories.)
