Yesterday was International Day of Happiness. There have been a Happy by Pharrell videos being made all around the world. Cristina of Slow Travel shared the Siena version in this Slow Travel post. As another Siena fan, I have to agree with Cristina that this is one of the best Happy by Pharrell videos out there. How can you not smile and be happy when watching this video?
