f(x)'s Victoria showed her 'folder-like' flexibility on a recent episode of SBS's "Strong Heart." Victoria revealed, "I attended a world-famous dance school that was extremely hard to enter. I first auditioned for it in elementary school. One of the judges asked me to give them my leg, so I did. They stretched my leg up to my ear and then took my other leg and stretched it to my other ear. They then asked me to fold my back, so I did. That's how I passed the audition." She concluded, "I sometimes sleep while doing the splits." She continued, "When I first joined f(x), my Korean wasn't that good so I used formal speech with everyone. I even told Sulli to have a good night in formal speech even though she is seven years my junior. One day, I was sleeping with my legs stretched out, my back bent, and my eyes open. I could see Sulli's bed from my position and she randomly caught my gaze. She got so scared, she almost cried. Since then though, we got a lot closer." Source: Newsen via Nate
