Hey, look at this! Girl's Generation (SNSD) on David Letterman. Even though it's hard tell these groups apart, this is one of the most famous K-pop groups in SoKo. I wonder if they know how lucky they are to be on set with three legends (especially Bill Murray, LOVE HIM). In any case, the girls are looking really hot so I'm sure Regis, Dave, and Bill are feeling pretty lucky themselves.
