SNSD's Sooyoung filmed an episode of Invincible Youth as a replacement of Yuri. Yuri was out because she had the swine flu for a few days over a week ago. On the show, she gave it her all as a one day guest. She cracked her jokes and impressed everyone with her humor. She even showed off her aegyo and beat Sunny's version of the "aegyo that calls for a punch" with her "aegyo that calls for a wooden stick." Then she blew everyone away with her chicken catching skills. I can't give her too many props for this one because we all know Park Ye Jin was the original queen of chicken catching during Family Outing. The episode airs on the 19th.
