Whose hand rests on Tae Yeon's shoulders?

If I had to choose a country that likes to "phoshop" their pictures, my vote would go to Korea. It's pretty apparent in magazines spreads, commercials, and well, even on netizen's cyworlds. Of course, this is not to say that American's don't do it as well, but Koreans pretty much photoshop till there's not much left of the original photo. Case in point: Girls Generation's recent Tweety photos. At first glance, the picture looks relatively normal. I mean I can overlook the fact the Jessica's jeans seem to be cut and pasted on top of Tae Yeon's hands. But then, crazy netizens make this discovery: Seeing that ghost hand on top of Tae Yeon's shoulders just gave me chills. I thought perhaps the girls took the pictures against a white backdrop, but now I'm starting to wonder if they just photoshopped out the background. After all, they did photoshop out whoever's body was attached to that hand. I hope they photoshop out that hand before they print the pictures in the magazine.
