Sometimes Jo Kwon's kkab can be a little too much, even for him. During the live broadcast of SBS;s "Inkigayo" on the 30th, the MCs interviewed Jewelry about their comeback stage, "Back It Up." At this time, the MCs requested Jewelry to show them a short performance of their new dance. Inspired by the fun choreography, Jo Kwon delivered a kkab version dance, but accidentally dropped his mic during the process. Because this was a live broadcast, the viewers caught the entire thing. The 2AM member quickly covered up his mistake by picking up his mic and saying, "I formally apologize,"making everyone laugh. Afterwards, Jo Kown posted on his Twitter, "This is the second time I tossed my mic high up in the air at 'Inkigayo'. Audio director, I'm really sorry. *Bow*" Source + Picture: Money Today via Star News
