Either SM Entertainment is a cruel company that makes H1N1 infected singers perform, or this was a pre-recorded performance. I think it was the latter. Either way, the “Oh!” performance today featured SNSD at an ice rink. It would’ve been nice if they were actually on ice skates, but I’m guessing not all of the members are that adept at ice skating. If you take a look at the small nuances of the performance, you’ll notice small tributes to Olympic figure skating champion, Kim Yuna. The “bond gun” at the end is one of the more obvious tributes. I thought it was quite well done, considering that no one slipped on the ice.
