This is, quite literally, Tim Cook’s happy dance. Yesterday was Earth Day, and Apple celebrated by bringing Pharrell to Apple’s Cupertino, California headquarters for a live performance. During the popular song Happy, several Apple executives hopped up on stage to join the performer’s background dancers. Among them were Phil Schiller, Eddy Cue and CEO Tim Cook, who definitely stole the show.
