Girls Generation/소녀시대 - Dance Practice for ‘Oh’

There’s something insane about this video of Korea’s most popular pop group practicing their dance routine for their new single and I can’t exactly figure out what it is.

The good news is, at least as all of the older (and I mean, I’m 26 now, so I can’t really talk) dudes are watching this thing, none of the girls are in high school anymore — the youngest one graduated from high school in the Winter.
