First off, Running Man is a famous Korean based Variety Show with viewers all over the world. 
First episode was broadcasted last July 10, 2010, which makes it 10 years running with more than 500 episodes and uncountable number of guests (Hollywood stars like Tom Cruise, Henry Cavill, Ryan Reynolds and Jackie Chan were once guested the show).
Started with 7 male members namely; Yoo Jae Suk, Ji Suk Jin, Kim Jong Kook, Kang Gary, Haha, Song Jong Ki and Lee Kwang Soo. Later, Song Ji Hyo, first female member was casted. Then, Lizzy. Due to work schedule, Lizzy had to leave the show then followed by Song Joong Ki after few episodes. By 2016, Kang Gary had to leave the show to focus more on his music career. Year later, 2 members were added, Jeon So Min and Yang Se Chan.
Running Man members showed their unique teamwork and friendship. I guess that what makes Running Man different from other variety shows, all members compliment each other. With whatever or whichever, one or more is lacking, the other members surely compensate. As a result, chaotic episodes were born. Hahaha. Laughter is a sure guarantee in RM. Plus the fact that we get the chance to see our favorite Kdrama artists and KPop Idols in their playful moods. 
Through RM, I discovered Ji Chang Wook and Park Seo Joon. Great actors, pleasing to look at (Hahaha) and most especially, funny which I think most girls are now looking for a man. ;)
So, if you want to take a break from your hectic and busy life, try watching Running Man. Or, just the short clips at Youtube. I caught the Running Man fever and I haven't found the cure yet. Or, I just don't want to be medicated as enjoy each and every episodes as well as each and every members.
