Gary and Song Ji Hyo revealed nervous hearts before playing a game.

In SBS "Running Man" aired today, Gary said, "I'm really nervous now that I'm about to play the stick cracker game with Song Ji Hyo. Are you going to close your eyes? You're not going to turn your head sideways, right?"

Gary then calmed himself down and looked to the ceiling.

While taking the game slowly, Gary suddenly grabbed Song Ji Hyo's head. Song Ji Hyo got surprised and pulled herself away from him in laughter.

They retried playing the game and successfully only left 1.2cm of the stick left.

Gary said, "Can we continue filming separately? I'll go for 7mm this time," arousing laughter.
