The NCAA Tournament's first round will get underway today, March 16th and tomorrow March, 17th which means you'll probably be doing a whole lot of nothing at work, or school, if you even decide to show up.

College basketball's annual tournament is one of the greatest events in all of sports, if not for the sheer hours and hours of hoops, for the cinderella stories and the epic buzzer beaters, like we saw in last year's National Championship game.

It's called March Madness for a reason. Take a look at five of the greatest buzzer beaters in NCAA Tournament history.
