Emotion. A good song by Carly Rae Jepsen and a great one by Destiny's Child. It's also something that UNC Men's Basketball Coach Roy Williams has a lot of.
And now, finally, thanks to Microsoft, we know exactly what he's feeling.

The Daily Tar Heel used the tool to run some old photos of Roy to see just how he was feeling and graphed the results:
