For those of you who aren't familiar with the show, 'No Voice' is a segment of the show where (normally) three guys go on and sing. Two of the three are decent while the third is completely off key. So combine that concept with 9 (well, 8. Kid leader Taeyeon couldn't make it for the recording because of ChinChin Radio) beautiful women and what do you get? Well... I'm not sure what to make of it, but the fans ate it up! The girls performed "Genie" first, and the crowd loved it so much they shouted for an encore. The girls answered with a performance of "Girl's Generation". The only bad part of this performance was Seohyun having to mess up on purpose. Her usual stellar performance was soiled for the sake of humor. Credit: allkpop
