SNSD's Yoona excited 1,400 servicemen on a recent Family Outing 2 episode after the whole cast showed up at a Kangwon-do service area and surprising them. The cast put on special performance as a treat for the servicemen and while the men generally enjoyed all the performances, the atmosphere turned red-hot when Yoona came on by herself. The 1,400 men went literally crazy as the cheering pierced everyone's ears including Yoona's as she put on a sexy Deja Vu chair dance routine (?) but she kind of stopped midway through the performance and we end with SNSD appearing as only a preview for next week. Nice job by the sneaky PD. http://www.youtube.com/watch?v=KmacvKv_AAM There were other performances as well of course like Shin Bong Sun doing HyunA's Change with Taecyeon, Jo Kwon performing 2AM's I Did Wrong with Taecyeon, etc. http://www.youtube.com/watch?v=dxU-0cclOyE http://www.youtube.com/watch?v=MMqwl--IWco Ji Sang Ryul and Yoon Sang Hyun did U-Go-Girl by Lee Hyori. http://www.youtube.com/watch?v=v4e6DGlzX4o Single Ladies rehearsal. http://www.youtube.com/watch?v=p30IN_WiQ10
