Has anyone ever filled out a perfect NCAA March Madness bracket?

There has never been an official, documented case of a perfect March Madness bracket. There are 9,223,372,036,854,775,808 different combinations of brackets in any given year, which is why many corporations will offer large prizes for a perfect bracket since the probability of a winner is low.
