Actor Lee Seung Gi revealed his 'silly character' chemistry with Lee Kwang Soo on "Running Man."

In the recent filming of SBS "Running Man," Lee Seung Gi appeared as the first guest of the year.

As this is Lee Seung Gi's third time on the show, he adapted to the setting as soon as he arrived, showing off his entertainment skills.

But he slipped and fell during one of the mission sets and showed slapstick when other members put ice down his shirt, bringing laughter to the set.

Lee Seung Gi also became the 'silly character' with Lee Kwang Soo and formed great chemistry with him.

This episode of "Running Man" will be aired on January 4.
