SNSD / Girls' Generation members Tiffany and Yuri have been hosting MBC's Music Core for a good while now. For being hosts, they get special perks, such as a whole segment to plug their second album "Oh!". During the segment they showed the teaser for "Oh!" and also did a few seconds of the choreography. The girls also mentioned that to see the full choreography, you'll have to wait until next week. Because on January 30th, they will make their official comeback stage on Music Core... ahh, what a tease. Thanks to Dorian for the tip and check out the segment below. http://www.youtube.com/watch?v=zf8QHEyZ0Io
