History
As part of Happy Sunday, Qualifications of Men replaced the second season of Immortal Music Classics in late March 2009. In the early episodes, the cast joked that their primary aim was not to disturb the ratings of sister segment 2 Days & 1 Night.
The original cast included the main MC Lee Kyung-kyu, who made his comeback into the Korean TV industry with this show; Kim Gook-jin, a comedian who previously attempted to become a professional golfer; Kim Tae-won, leader of the legendary rock-ballad band Boohwal; Lee Yoon-seok, a comedian known for his doctor's degree and conversely his ridiculously weak strength (though since joining the show, Kim Tae-won took over his title of "Weakling of the nation"); Yoon Hyung-bin, a comedian from the show Gag Concert; and actors Lee Jung-jin and Kim Sung-min.
The cast went through a variety of physically and emotionally taxing missions, usually spanning over 24 hours, performing the likes of serving mandatory military service again, crying, becoming employees of random companies, not smoking for a day, wake-boarding, singing in a choir, participating in an amusement park parade show, and forming an amateur band. The most memorable moment for the program was when 2 of the members (Kim Gook-jin and Kim Sung-min) was selected as a guest for the United States Air Force Thunderbirds Acrobatic Team, during their 2009 Far East Tour at Osan Air Base, in South Korea. For the Choir episodes, both of the Choir teams won awards (with guest Kolleen Park and Kim Tae-won as conductors).
In late 2010, Kim Sung-min was dropped from the program after being arrested for drug use. He was sentenced to 2 years and 6 months in prison for meth use and smuggling, suspended for 4 years.
This brief starts where responsible research should: with the source description of “Qualifications of Men” as happy Sunday reality-variety show aired on KBS2. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as happy Sunday reality-variety show aired on KBS2. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 29, 2026. The linked authority identifier is Q13593403. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2009, 2013, 2012 and 2010.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
