There are more than a bajillion reasons why you'll never pick a perfect NCAA college basketball tournament. But this year, there are a billion reasons why you've got to at least make one half-cocked attempt at it.

Warren Buffett, without putting his pinkie finger to the corner of his mouth, has put up $1 billion of his own cash (his estimated net worth: $53.5 billion), betting that you can't go to a legal loan shark's website and produce a flawless forecast of how 63 games will play out over the next few weeks.

The odds are stacked in his favor, as usual.

Anyone attempting this feat with some willy-nilly strategy has a 1 in 9,223,372,036,854,775,808 of getting it right. And if you actually do know something about the sport, the odds are greatly reduced to 1 in 128 billion - or not as good as flipping a coin 37 times and having it come up heads in each instance.

No one in recorded history has perfected this feat. ESPN has run an online contest going back to 1998, and nothing has even been close, which includes 30 million entries.'/>
