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
