If Thursday night's March Madness action proved anything, it's that Xavier is the tournament's Cinderella story.

The 11 seed shocked Arizona, and the internet reacted accordingly to say the least.

The best part of Xavier's victory, though, for some fans was what happened off the court after.

As many people know, Bill Murray is a big fan of the Musketeers and his son, Luke Murray, is an assistant coach of the team.

After the final buzzer sounded, Bill's reaction was absolutely priceless.

Is anyone having a better year than Murray?  First, his Cubs win the World Series and now Xavier is on the verge of making it to the Final Four if they can beat the top seed, Gonzaga, in their next game.

The Gonzaga and Xavier game is Saturday at 6pm ET, and you can watch it on TSN.
