Most of the songs in 2009 came with dances, which boosted up the popularity of the artist even more. On the Christmas Special of Music Bank, MBLAQ and BEAST joined together and reenacted the most popular dances from this year. Check out the joint performance below consisting of the Brown Eyed Girls' saucy hip dance, Girls Generation's Gee dance, 2PM's slow-mo running dance, and more! The two rookie groups are rivals, but behind the stage, we all know that they are actually friends and this performance proved that friendship. Can this be a formation of the second Dirty Eyed Girls? Or was it too serious to be even compared to the One Day members' hilarious performance? You decide. Check out their group performances too.
