Yoo Jae-Seok
Yoo Jae-Seok (Hangul 유재석 or spelled Yu Jae-Suk, born on 14th August 1972) is a South Korean comedian and television comedy show host. Nicknamed as "MC of the nation" (국민 MC), netizens voted him the most popular Korean comedian for five consecutive years since 2004. He has hosted several variety shows in South Korea, including the hugely popular program Infinite Challenge. Nicknamed "The Grasshopper", due to early appearances dressed as a grasshopper, he is now known for his quick wit and likability with most demographics, and has established himself as one of Korea's top comedians and TV personalities.
Biography
Yoo Jae-Suk was the first child in his family. He had two younger sisters. He was born on 14th August 1972 in Seoul, South Korea. Yoo Jae-Suk attended the Seoul Institute of the Arts, but had been unable to receive his degree due to his hectic schedule as a comedian.

His television debut was on the KBS Comedian Festival (for college students) in 1991, performing a parody of a commercial with Choi Seung-Gyung (Hangul: 최승경). In Infinity Challenge, him dancing to a cover of the song "Step by Step" by New Kids on the Block was shown as one of his early memorable moments. After nine years of hard times, in 2000, he hosted a program called Live and Enjoy Together (Dong-guh-dong-lak), thanks to Choi Jin-Sil's recommendation. The program became instantly popular, and since then, Jae-Seok began to host many other variety programs. His potentiality was fully shown when he co-hosted a program called The Crash of MCs (MC 대격돌 – 공포의 쿵쿵따) with Kang Ho-Dong, Lee Hui-Jae and Kim Han-Seok.

His first Grand Prix was for a program called Happy Together Friends, which concept based on TV personalities trying to find their school friends (five of them) out of many (false friends) who are sitting behind the desk. The show brought reminiscence upon the viewers' school days, and became very popular. This Grand Prix is even more memorable, not just because it was Jae-Seok's first one, but it was from the broadcasting system where he debuted.

He hosted the shows X-Man, which soon grew to be very popular, and thus one of the most viewed shows in Korea. During those times, he gained much more popularity and many programs began to nickname Jae-Seok as "MC of the Nation." However, after few years of constant airing, the program was canceled due to failing ratings as well as absence of new ideas, and Jae-Seok went on to host its replacement shows, New X-Man, Old TV (in which guests would re-enact classic TV series), and Haja! Go! (Let's Do It) for SBS, which were all canceled soon, due to low ratings on Sunday evening. However, X-Man has gone on to success in international syndication.

Jae-Seok is a part of the cast of the top-rated comic variety program Muhan Dojeon (무한도전), as the host-in-chief since 2005. Initially a six-member cast, Haha left the program as he was drafted to serve his mandatory military service and was replaced by Shinhwa's Junjin. The program wasn't popular when it first aired, but by the time Season 3 aired in 2006, the concept and format of "variety & reality program" became so popular, and Infinite Challenge became the forerunner of so many programs to follow with the same or similar format. Infinite Challenge is possibly the best program for Jae-Seok, for he met his wife Na Gyoung-Eun (나경은) during season 2, and with the rising popularity and significant effect on general public, Jae-Seok got even more famous. He ended up getting total of three Grand Prix (in 2006, 2007 and 2009) with the program.

Jae-Seok also co-hosts Come to Play (놀러와) with Kim Won-Hee and Happy Together Season 3 (해피 투게더 3) with Park Myung-Soo, Park Mi-Seon and Shin Bong-Seon. Jae-Seok hosted these talk shows for a long period of time (both over 5 years), but the ratings have been constantly high throughout the years. Similar, yet very different, Jae-Seok tries his best to differentiate his hosting styles, both based on the guests and the settings they are situated in.

After those replacement shows on SBS, on 15th June 2008, Jae-Seok, along with Lee Hyori, Yoon Jong-Shin, Kim Soo-Ro, Lee Chun Hee, Kang Dae-Sung, Park Ye-Jin and Kim Jong Kook (since episode 19) are the hosts and family members of Family Outing (Korean: 패밀리가 떴다), part of SBS's Good Sunday lineup. Since then, Family Outing has become one of the top-rated shows in Korea, consistently achieving the highest ratings at Sunday mid-afternoon time-slot (especially during the first and second quarters of 2009). However, with various problems and scandals regarding the program, and by the end of 2009 and beginning of 2010, a rumor of Yoo not continuing his contract with Family Outing was raised. By the time of his contract expiration, Family Outing rating wasn't same as that of beginning of 2009, and Season 1 was brought to an end (on 2010.02.14 with Family Awards).

On 6th July 2008, Yoo Jae-Seok married MBC announcer Na Gyoung-Eun (나경은) who has also worked on the show Infinite Challenge. Jae-Seok and his wife welcomed their first child, a son, on May 1, 2010. He is a Buddhist.
From July 11, 2010, he is hosting in a variety show called Running Man together with Ji Suk Jin, Kim Jong Kook, Kang Hee-gun/Gary (LeeSsang), Ha Dong Hoon, Song Ji-hyo,Lee Kwang Soo and Song Joong-Ki(who has since left the show as of episode 41 to focus on his acting career).

On Infinite Challenge
On Infinite Challenge as the host-in-chief, he leads all Infinite Challenge members to reach the goal of each episode. Due to his leadership presented to this program, a new kind of cult has been created called "Infinite Jaeseok Cult" (Korean: 무한재석교) and he becomes a spiritual leader of this false-religion. The official followers are Ha Ha and Noh Hong-cheol (from the episode of Season 3, episode 61), and the official motto is "I shall make you laugh" (내가 너희를 웃기게 하리라).

Also during the New Zealand series, he got caught smuggling pornographic videos during the baggage check, which was hidden by the second host in charge: Park Myung-Soo. This sketch was well received by the Korean netizens and Jae-Seok became "Ero Jae-Seok". Even now, over seventy episodes later, he still is made fun of for watching pornographic videos which he hadn't watched.

He has been called "Class-president Yoo" (유 반장) for so many episodes of Muhan Dojun, but since "Palace Millionaire" special (Slumdog Millionaire parody, where Infinite Challenge members tour old palaces in Seoul), Yoo has been nicknamed Delinquent Yoo (날 유), for having meetings with girls at these palaces back when he was a high school student. His most recent nickname has been "An Animal Racer" (짐승 레이서), "A Genius Racer" (천재 레이서), and "Yoomacher" (유 마허), thanks to his excellent driving skills shown during Infinite Challenge Formula One (F1) Special.

On Family Outing
The vital power of the instant success of Family Outing has been the characters' relationships. Two of the most successful character pairings has been "The Nation's siblings" (국민 남매) with Lee Hyo-ri and "Dumb and Dumber" with Dae-Sung of Big Bang. Yoo has been the driving force of those two character relationships, as program's host-in-chief and regular member of the family.

On Running Man
Although he is one of the weak ones, Jae-Seok is always portrayed as the rival of Kim Jong Kook. He often calls himself "Yooruce Willis" (유르스 윌리스) when being chased by Kim "Sparta" Kook but he often gets caught in the end. He is also often labelled as the "Icon of Betrayal" because of one episode (38) wherein he has to lie to and eliminate all his teammates. However, in later episodes, he became one of the top three strongest members of Running Man who could potentially pose a threat to win any of his missions.

On TV talk shows
As the main host of two talk shows (Come to Play and Happy Together Season 3), Jae-Seok tries to differentiate his hosting (MC-ing) styles. In Come to Play, he focuses more on guests' episodes, rather than his own (This can be violated when his close friends appear on the show). His remarks and reactions flow even if the guest is new on any kind of variety programs, thus makes Come to Play very heartwarming to watch. Happy Together Season 3 is little bit different in a sense that the setting is much more intimate (in a sauna locker room), and Jae-Seok's ad-libs shine brilliantly.
