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.

In the interview, SISTAR revealed their Christmas wish: "To leave our schedule." The follow-up question asked what they would do if they picked up a chance to escape for the day.  Hyorin said she'd go to the club, Soyu wanted to go on an amusement park date, and Dasom chose an instant vacation around the world.

Check out some performances from SISTAR, 2AM, Dynamic Duo, Gummy, Park Jung Hyun, and Fly to the Sky below!
