Buffett issues a March Madness bracket challenge to all employees who work at Berkshire Hathaway companies. If you can put together a perfect bracket, Buffett will award you $1 million. The only problem is that perfect brackets don't exist. It's basically impossible to do. So, unfortunately, Warren has to keep his money.

After weeks of anticipation and speculation, the bracket-filling finally can begin today as the 68-team fields for the NCAA men's and women's basketball tournaments are revealed. "Selection Sunday" will unveil which teams made the March Madness tournaments (and which "bubble" teams were left disappointed) that will unfold over the course of four regionals to will determine the Final Four national semifinals.
