Girls' Generation is finally making their appearance as a whole group on the JTBC show 'Knowing Brothers'!

In the preview, Super Junior's Heechul is seen kneeling down in front of Girls' Generation stricken with fear and asking, "What did I do that was so wrong?" In which Sooyoung jokingly responded, "We'll shut our mouth so you do the same." Heechul also joked back by saying that it more feels like 'Knowing Noonims' than 'Knowing Brothers'. The group is also seen having fun with the cast of the show by dancing to different tunes and playing various games. From the preview alone, it's possible to see that Girls' Generation isn't just a veteran on the stage but also on variety shows.
