Pharrell Williams is a rare commodity: articulate, compassionate, charismatic, and a darned talented musician. His hit HAPPY, from the film Despicable Me 2, has sold millions. No wonder -- it's uplifting, aspirational, easy to dance to, and, well, it makes me happy just to have it floating around in my head. I promise this short video will make you smile, or dance, or clap, or all three. And we should do more of all of those, every day. Be happy, and share the happiness.
