Shake it did Gary and Hyorin on the July 10 episode of 'Running Man'! And pretty enthusiastically at that. While the other couples danced to the music without much vigor, Gary and Hyorin shook things up (quite literally) by wriggling every limb with all their might. Hyorin got busy shakin' her booty and Gary added in some jazz hands for good measure.
Let's give a round of applause for the dancing king and queen, folks.
