Actor So Ji Sub recently shot an action-filled CF for Powerade. While reading a book like a classy gentleman in the middle of the road, So Ji Sub was challenged to a match of tennis by a Roger Federer look alike. Grabbing his iPad like a pro, the two exchanged fierce smashes with So Ji Sub ultimately winning over him with the burst of energy he got by drinking his Powerade. True? Not so much. But do drink Powerade because heartthrob So Ji Sub has endorsed it! Thanks to Alex for the tip!
