On the December 30 episode of “Running Man,” the cast including Lee Kwang Soo and Kim Jong Kook went to the beach for one of their challenges.
It is not known whether Lee Kwang Soo’s pants were a size too big, but for whatever reason, his pants kept falling off. While Kim Jong Kook and Lee Kwang Soo were racing each other, Lee Kwang Soo kept having to pull up his pants to keep them from completely falling off.
It was right when Lee Kwang Soo was about to cross the finish line ahead of Kim Jong Kook when the embarrassing situation occurred. Seeing that Lee Kwang Soo’s pants were about to fall off, Kim Jong Kook yelled “Pants!” At this point, viewers could see Lee Kwang Soo’s underwear, prompting TV editors to cover his behind with a smiley face. The “Running Man” members could not hold their laughter while watching Lee Kwang Soo try to fix the embarrassing ordeal he found himself in.
