On the June 24 episode of 'Unnies' Slam Dunk,' J.Y. Park tested the members to see how much their dancing has improved. 

As soon as Tiffany showed up at the practice room, the other cast members cheered, "The ace is here!" and welcomed her with open arms. However, unlike the rest of the 'Unnies' Slam Dunk' crew, Tiffany was looking downer than usual. The singer, wearing an apologetic expression, sank to her knees as soon as she walked into the studio. When the members looked at her with puzzled faces, Tiffany explained, "I'm so sorry but I didn't practice. Once preparations for my performances are over, I will live at JYP for a week." 

Soon thereafter, J.Y. Park himself showed up at the studio, and Tiffany turned to him to apologize once again. She said, "I didn't get to practice much. I'm sorry. I'm not good at multi-tasking." Jessi also took the opportunity to 'fess up, telling J.Y. Park, "Tiffany and I didn't get to prepare. But we'll work the hardest."

Though Tiffany and Jessi didn't prepare, it seems Hong Jin Kyung was born prepared! Noting the her confidence, J.Y. Park complimented Hong Jin Kyung, "You seem to be full of confidence today." Unfortunately, it seems Hong Jin Kyung didn't practice as much as she claimed, as she messed up the dance move near the end.

Chin up, girls! Practice (and more practice) makes perfect!
