Happy Friday.

It's Friday. I get to see my wife tonight. We are going to a Royals game. Just so much to be happy about. Then, one of my students shows us this video of Pentatonix singing a collection of popular songs through the ages. You know what all of these things have in common? They are fun. If you haven't ever listened to Pentatonix before you should really check them out, especially if you were a fan of Pitch Perfect (the first one, we all know that second one was just a bad nightmare). Happy Friday and enjoy listening.
