Just when you thought the K-Pop phenomenon was finally over, this seven month old baby brings 'Gangnam Style' back to the spotlight. On Friday, YouTube user John Karam uploaded this video of a baby riding an invisible horse (a.k.a. dancing) to PSY's hit song, 'Gangnam Style'. Since then, the video has been watched over 900,000 times. Like its author wrote on the clip's title, this one is a "must watch."
