Happy Sunday

In late November 2008, Happy Sunday had a revamp of its shows keeping 1 Night 2 Days as the second segment and bringing back Immortal Songs which was previously liked by viewers.

However, in late March, Immortal Songs ended once again and was replaced with Qualifications of Men, making Happy Sunday an all-male cast, with a total of 14 members.

Both MBC and SBS have done this to record better TV ratings, which is important in South Korea media to prove the show's popularity.

On September 13, 2004, voice (dubbing) artist and 2003 KBS Entertainment Awards Grand Prize (Daesang) winner, Jang Jeong-jin (장정진), was recording for The Lord of the Alley (골목의 제왕) segment where he had to eat rice cakes during a game and was later hospitalized.

In the segment The Return of Superman (Korean: 슈퍼맨이 돌아왔다), celebrity fathers spend 48 hours with their children without their mothers.

This variety show has a school theme, where male celebrity guests come and firstly try to partner with the heroines of their choice, through dance (usually) or special performances.

Hosted by Jee Seok-jin, High-Five focuses on having its five female stars try out different jobs; over the course of the show, they have become flight attendants, farmer, stuntwomen, and police officers.

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.

The first episode aired June 1, 2008 replacing High-Five, while retaining Hyun Young and Jo Hye-ryun as part of the cast.

Delicious Quiz was a food-based variety show where they traveled around Korea visiting famous restaurants or places related to food.

Olympic stars compete in simple yet nostalgic games and activities on a set created to look like a classroom with celebrities as their competitors.

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.

Happy Sunday brought back Immortal Songs with the same hosts, Shin Jung-hwan, Tak Jae-hoon and Kim Sung-eun.

[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.

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.

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.

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.
