The odds of picking a perfect bracket in the NCAA men's basketball tournament are really, really small. So small, in fact, that many mathematicians differ on the actual estimation of the odds.

Some believe it's as low as 1 in 9,223,372,036,854,775,808 (or 1 in 9.2 quintillion, for those who skipped the last 18 digits), while others, including Jeff Bergen, a professor at DePaul, think it's as "high" as 1 in 128 billion. Either way, picking all 63 games (excluding the First Four games) correctly is next to impossible.
