Get excited to see the quirky side of Girls' Generation once again!

The ever lovable, easygoing, and cool members are going to be on 'Running Man' this weekend, so the show dropped a few preview pictures as well as a preview clip of the girls doing crazy dances in a dance-off!

They are not only full of laughs but they also provide a lot of laughs for the viewers.  Look at them body waves!  Whip that hair!  They're having so much fun that it's infectious.

Make sure you watch it air on July 5 for their mission parades.
