In an upcoming episode of KBS JOY's 'Super Junior and SISTAR's Hello Baby', Leeteuk made a surprise visit to SISTAR's dorm! SISTAR's dorm has never been shown on TV before, and even their managers have been barred from entering the sacred place.  Despite the members blocking him from entering, Leeteuk became the first ever male to set foot in their dorm. Leeteuk immediately put the opportunity to use by bringing out his variety skills.  Not only did he dig around every corner of their rooms, but even revealed their diaries and searched for any traces of possible boyfriends. Check out other fun scenes like Super Junior's reaction to Leeteuk becoming a father and SISTAR's cute display of aegyo in an effort to win the affections of baby Kyumin.  It all airs on September 2nd at 12 AM KST!
