March Madness has already lived up to its name.
Several upsets in Thursday and Friday's NCAA men's basketball tournament games wreaked havoc on brackets. After 15-seed Middle Tennessee State's shocking win over Michigan State and Iowa's win over Temple University, just three brackets of the roughly 13 million submitted remained perfect in ESPN's Tournament Challenge.
No, really, just three.
About 0.1 percent of the entries at CBSSports.com were unblemished as of Friday morning, but Middle Tennessee State's victory likely ruined many of those.
CBS declined to say how many brackets were submitted.
