VIDEO: Michael Emerson sings 'Happy' on 'Arsenio'

Michael Emerson of Person of Interest sang 'Happy' on The Arsenio Hall Show in character!

Epic!

One of my favorite covers of Pharrell William's hit song.

Memerson should make this a regular thing.

Michael Emerson isn't the dark, twisted character you see on TV. No, he's happy. He's so happy that he's singing "Happy." It's dark and twisted.
