There was a Christmas party on 'Yoo Hee Yeol's Sketchbook' on December 19 for the upcoming holidays!

Stars gathered to put on fun and somewhat peculiar performances as they costumed themselves up like bears and other strange creatures to sing their hearts out. SISTAR wore fuzzy bear-like costumes with glowing hearts on their bottoms as they performed "Touch My Body" while 2AM painted clocks on their faces while taking on their soulful ballad.�
