Person of Interest’s Michael Emerson isn’t the dark twisted character you see on TV. Emerson stopped by The Arsenio Hall Show on Tuesday night to prove that he’s “not that sinister, intense person. I’m a positive, optimistic and fun loving guy!” who is quite happy. So happy, in fact, that he’s singing Pharrell’s big hit “Happy.” He even brought along his own hat! Ladies and Gentleman, performing his own take of “Happy,” we present to you, Michael Emerson. Clap along & enjoy!
