Because of the stars' backgrounds, comic twists and events are often added in during training. At the show's start, comedian Jo Hye-ryun, entertainer Hyun Young, singer Chae Yeon, MC Park Kyung-lim, and actress Kim Min-sun were the High-Five stars. Due to filming commitments, Kim had to leave the show on its November 4, 2007 broadcast. She was replaced by news anchor Lee Jung-min. This show was replaced by Delicious Quiz.

The games will require the "athletes" to use simple school necessities like chairs, desks, mops and even buckets. Aiming to bring a more interesting and fun school environment, the show combined elements of sport and school activities with the help of sports stars and celebrities. This show was short lived and it was not replaced; instead, the 2 segments Kko Kko Tours Single♥Single and 1 Night 2 Days both extended their airtime.

• Originally aired: September 21, 2008 - November 23, 2008

Celebrities invite someone they're interested in and get to know them during a trip. Audiences will get to see the true, sensitive side of celebrities as they open their hearts on air.

The show was replaced with a new season of Immortal Songs which had been previously cancelled.[13]

Immortal Songs (Korean: 불후의 명곡; Hanja: 不朽의 明曲; RR: Bulhu-ui Myeong-gok) was co-hosted by former Country Kko Kko partners Shin Jung-hwan and Tak Jae-hoon. Although the show initially had various co-hosts, Kim Sung-eun became the final permanent host alongside Shin and Tak. The special guest for the week is their "vocal coach," usually a famous Korean singer, although sometimes record producers and composers have appeared as the special guest. During the course of the show, the special guest's top singles (as voted by netizens) are revealed and the "students" must sing karaoke-style. At the end of the show, the best singer/student is chosen by the special guest and receives a special prize. This segment started from Kim Won-joon's episode where he brought in presents on his own accord. The show has typically showcased older singers from the past who may or may not be still active in the entertainment industry, including Lee Seung-chul and Kim Heung-gook. However they have also had episodes featuring more recent artists, including S.E.S., in recognition of their 10th anniversary since debut, as well as Sung Si-kyung just before he left for military service in July 2008. This show aired its final episode on September 14, 2008 and was replaced by Kko Kko Tours Single♥Single.

Happy Sunday brought back Immortal Songs with the same hosts, Shin Jung-hwan, Tak Jae-hoon and Kim Sung-eun. Its first returning episode began airing November 30, 2008, replacing Kko Kko Tours Single♥Single. Kicking off the second season, Patti Kim was the special guest.[14] Patti Kim was the first Korean artist to be invited and perform on Japan's NHK network as well as The Johnny Carson Show in Las Vegas, United States.[15] In season 1, Patti Kim was one of the guests that they wanted to invite on the show but was unable to. This segment was cancelled in late March 2009 and has since been replaced with Qualifications of Men.

• Originally aired: March 29, 2009 - April 7, 2013
• Cast: Lee Kyung-kyu, Kim Gook-jin, Kim Tae-won, Lee Yoon-seok, Yoon Hyung-bin, Joo Sang-wook, Kim Jun-ho
• Former members: Kim Sung-min, Lee Jung-jin, Yang Joon-hyuk, Jun Hyun-moo

Qualifications of Men (Korean: 남자의 자격; Hanja: 男子의 資格; also known as Qualifying Men or The Qualities of a Man), replaced the second season of Immortal Songs in late March 2009. It is a show where a group of mostly middle-aged male celebrities try to complete missions (deemed to be of a quality required of a "qualifying man") given by the producer or sometimes thought of by the members.

In the first episodes, the cast joked that their primary aim was not to disturb the ratings of 1 Night 2 Days. However, the show was an unexpected success and rivaled their sister corner 1N2D in the 2009 KBS Entertainment Awards. The cast includes the main MC Lee Kyung-kyu, who made his comeback into the Korean TV industry with this show; Kim Gook-jin, a famous comedian who recently came back from attempting 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 has virtually taken over his title of "Weakling of the nation"); Yoon Hyung-bin, a famous comedian from the show Gag Concert who frequently compares himself to Lee Jung-jin, although often to no avail; Yang Joon-hyuk, one of the greatest players in Korean baseball history and currently holds the records for home runs, RBI, and best batting average; and Jun Hyun-moo, a KBS news announcer and reporter known for his variety and comedic skills, who is rising in the entertainment world (also known for his parody of SHINee's "Lucifer" dance).

The cast has been 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 former member 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 team won awards (the most recent was the 2nd Place during the KBS National Choir Contest "The Harmony", with Kim Tae-won as a conductor).

In late 2010, Kim Sung-min was dropped from the program after being arrested for meth use and smuggling. He was sentenced to 2 years and 6 months in prison, suspended for 4 years.[16]

On April 10, 2011, Korean baseball legend Yang Joon-hyuk made his debut as a member of the show.

On May 8, 2011, Lee Jung-jin appeared in his final episode and Jun Hyun-moo became the newest and 7th member of the show.

On July 31, 2012, Yang Joon-hyuk and Jun Hyun-moo left the show, and 2 new members—actor Joo Sang-wook and Gag Concert comedian Kim Jun-ho—joined the crew.[17]

Qualifications of Men initially maintained good ratings; in 2009, it placed second among the most viewed Sunday night programs for 16 weeks with more than 30% viewership ratings.[18] But after four years on air, ratings dropped, until it was overtaken in popularity by MBC's Dad! Where Are We Going?, which premiered in 2013.[19] KBS cancelled the show, and it aired its last episode on April 7, 2013.[20] The show had begun in 2010 under the catchphrase, "101 things to do before you die," but with its cancellation four years later, the show's raison d'être was unfinished, with the program coming to a close before the cast members were able to finish filling out the list of 101 things, only getting up to #94.[21]

Star Family Show Mamma Mia (Korean: 스타 패밀리쇼 맘마미아; also known simply as Mamma Mia) is a talk show in which Korean celebrities and popular figures bring their mothers.[22] One of the hosts, Choi Minho left the show after five episodes; he was replaced by Cho Kyuhyun beginning May 19, 2013.[23] This segment was moved to Wednesday nights. Mamma Mia was replaced with Superman Return on November 3, 2013 . Then, on 18 October, 2013 KyuHyun had announced to leave the show because of the overlap schedule with 'Radio Star' on MBC.[24] The regular on the show and comedian, Heo GyeongHwan will replace KyuHyun's place as the MC of the show.[25]
