Actually, it was probably the other way around. In any regards, TVXQ made a random "surprise attack," on a female high school and performed the "Hahaha" campaign song. This campaign is currently sponsored by Samsung, due to the tough economy.
It goes without saying, the high schoolers were ecstatic when they appeared. And panties flew all around the classroom during the performance - just kidding.
One pissed off high school chick voiced out:
"Why the hell did TVXQ choose that school? What's the standard in choosing a high school?"The "Hahaha" song is originally by rock band "Jaurim." Check out the "attack" below.
Thanks to Passyx9 for the video.
