Video: Harry Shum, Jr. dances AND sings on Glee!

On most episodes of Glee, Mike (played by The LXD's Harry Shum, Jr.) doesn't even get to talk. On the October 12 episode called "Duets" he even got to sing! Here, Mike and Tina (played by Jenna Ushkowitz) go for the laugh with "Sing" from A Chorus Line.
