He said in the beginning of the show that he, a former member of the Korean YMCA's Junior Sports Team (YMCA 아기스포츠단), swam from the middle of the sea to the beach in his youth. The staff decided to prove his argument. It was eventually proved false (he failed to keep up his pace in the middle of the Bay of Gyeonggi to reach Songdo beachside).

• Seoul city touring race - First come, first served ('서울구경 선착순 한명', Part 1, Individual races)
  • Rule: All members of Muhan Dojeon travel with their 5000won (about US$5.50 or €4) -valued (Seoul Metropolitan) transportation card from their home to go to Palgakjeong, Namsan (남산 팔각정, near N Seoul Tower) by themselves, without any staff or their managers.
  • Processes and Results

• Seoul city touring race - First come, first served ('서울구경 선착순 한명', Part 2, Team-challenges)
  • Rule: Top 3 medalists can nominate a partner for this team-adventure. All teams should start from Namsan to the en route point, the Dosan Memorial Park in Gangnam-gu. After then, all teams should capture 4 pieces of Korean letters: 'Mu' (무), 'han' (한), 'Do' (도), 'jeon' (전) (the name of the programme in Korean) with their cameras before finishing this race to go to the MBC Headquarters in Yeouido. However, due to the heavy rainfall which impeded the race, not all the mission was accomplished. (But all of the prize-computer supplies were seized by the staff.)
  • Processes and Results

• Do-it-yourself (네 멋대로 해라) special episodes, Part 1 - Each member of Muhan Dojeon serves as Executive producer (and also as a presenter) for 10 or more minutes of their self-made segments. The point of this challenge was to give a summer holiday to the hard-working staff; however, the entire staff of this programme decided to give up their vacation to fix this ridiculous 'D.I.Y.' episode. Park Myeong-su's and Jeong Hyeong-don's segments aired (other segments were broadcast on September 8, 2007).
  • Geo-seong Show with Park Myeong-su - to create an ordinary talk show; however, the contents of this show were dramatically changed to resemble The Jerry Springer Show (as a guest—who later served as a host--Yu Jae-seok strongly argued). It was hosted and produced by Park Myeong-su, Jeong Jun-ha served as a joint panelist, and music was performed by the band Terrible (No Hongchul, Jeong Hyeong-don and Ha Ha).
    • This show was sponsored—which included a pun based on the name of companies by its staff—by 'Piggy & Superb-piggy' (뚱보&뚱뚱보), 'Magic Shoes corp.' (주식회사 마법의 구두), 'Chivas Dae-gal' (시바스 대갈), 'Hyeong-don's supper' (형돈이 야식), 'M.A. Ha's English Academy' (하석사 영어교실), 'Father's Wig Corp.' (주식회사 아버지 가발), 'Muhan Rox' (무한락스), 'Yu's video' (유씨네 비디오), and 'Gas Park myeong-su' (까스 박명수).
  • Change - Hosted and produced by an awkward comedian, Jeong Hyeong-don. The aim of this segment was to disguise their characters, so that all members could recognize their public images, and to care for other members to build a strong unity of this programme. Yu Jae-seok's performance (Yu Geo-seong, a character that imitated Park Myeong-su's) was a huge sensation.
    • Yu Jae-seok played Yu Geo-seong, Park Myeong-su became Park Jun-ha, Jeong Jun-ha served as Jeong Ha, No Hongchul was No Hyeong-don, Ha Ha was Ha Hongchul, and the host-for-the-day Jeong Hyeong-don was disguised as Jeong Ban-jang.

• Do-it-yourself (네 멋대로 해라) special episodes, Part 2.
  • Han-ip-mann (한입만) - Presented and produced by Jeong Jun-ha. The purpose of this segment was to go to several restaurants in Yeouido and for each of the members to try a spoonful of meals from its beloved viewers. During their surprise visit (to challenge their mission), everyone who met the Muhan Dojeon members was cheered warmly. However, only Jeong Hyeong-don's last mission wasn't accomplished.
  • Boys without fear (겁없는 녀석들) - Presented and produced by Yu Jae-seok. The aim of this segment was to overcome individual fears. With professional hypnosis treatment for its members (except Jeong Hyeong-don and Ha Ha), they took the challenge of firewalking to heal their fears; however, only the host-in-chief of this programme Yu Jae-seok succeeded (after his mission was accomplished, the others ran and faded away). During a treatment, No Hongchul's unusual moment of crying like a baby was a huge sensation to its viewers.

• Do-it-yourself (네 멋대로 해라) - Part 3
  • M.A. Ha Ha's "Ask Me Anything" (석사 하하의 무엇이든 물어보세요) - Presented and produced by Ha Ha; his segment was originally supposed to air the previous week (September 8), but due to the lack of time, it was pushed to September 15. Ha Ha takes phone calls from elementary, middle, and high school students.
    • Jeong Hyeong-don served as an operator. The main character of this segment Ha Ha gives professional advice, and Jeong Jun-ha, No Hongchul and Park Myeong-su acted as an opinion panel. Yu Jae-seok again served as a host of this segment.
    • These are the questions M.A. Ha was asked:
      • An elementary-school student asked how to get back his 3000won from his friends (who loaned it from him).
      • A middle-school student asked Myeong-su how to remove a black stain (흑채) for her grandmother.
      • A high-school student questioned (and later teased) M.A. Ha what the word Sparta meant, and its origin.
• 'Sseokso & The City' (썩소 앤 더 시티) - The theme of this episode was to answer a question for Muhan Dojeon: what is the meaning of Fashion?
  • Please, come Early (일찍 와주길 바래) - The time-target to arrive at the outside studio was 10:00 AM.
    • The earliest member to arrive that day, host-in-chief Yu Jae-seok, arrived at 09:57 AM. No Hongchul and Jeong Jun-ha arrived a minute later (09:58 AM). Jeong Hyeong-don was about 10 minutes late (arrived at 10:10 AM), and just after that, Park Myeong-su and Ha Ha arrived at the set holding hands.
  • Mission of the day (with Fashion designer Park Mann-hyeon): within a limited budget of 300,000won, each member should create a 'Party Look' in a fashion mall in Dongdaemoon. The title of 'Best Dresser' went to Jeong Jun-ha, and the 'Fashion Terrorist' (the worst dresser) was Jeong Hyeong-don, with a narrow margin against Yu Jae-seok.
  • Gorgeous Dinner party with Doenjang-guys (된장남들의 저녁식사) - During their meeting, they even criticized each member.

• Hangawi Special Invitation - Kim Yu-Na (김연아, a world-class figure skater) in Muhan Dojeon
  • Preparation segments - As always, all Muhan Dojeon Members have special training before meeting a sportsperson. It was filmed in the middle of the night (from 01:30 AM to 05:30 AM), so that all members were eventually exhausted.
    • Short Track Individual race (3 laps) - Ha Ha got a victory, No Hongchul came 2nd, and Yu Jae-seok placed 3rd.
    • Short Track Relay (6 laps) - Team Dol+I (돌+아이, No Hongchul, Jeong Jun-ha and Jeong Hyeong-don) won, therefore, the team Little Bitty (땅꼬마, Ha Ha, Yu Jae-seok and Park Myeong-su) should get their hair permed (that will be broadcast later).
    • Round & Round Challenge (대결 빙글빙글) - 1:1 match, to focus more on its processes with lots of slapstick comedy scenes than its results. A challenger should round a circle for 10 (later 15) laps on a tumbler. After that, the challenger should cross over the beam and catch a banana, the 'bread of life' for all Muhan Dojeon members. During a segment, Park Myeong-su performed a traditional Korean play Geo-shaung Jeon (마당놀이 거셩전).
  • Yu-na, Catch me (if you can)! - All members should run from Kim Yu-Na. She is expected to catch 6 members within 5 minutes. She succeeded easily in 3 minutes, but the Muhan Dojeon members were totally exhausted.
  • Boys and 'Ah-jeo-ssi's, Catch me! - the roles were switched from 'Yu-na, Catch me!'; this time Kim Yu-na had to avoid being caught by Muhan Dojeon members. The members were at a loss against her truly-fast running speed and zig-zagging to avoid capture.
  • Television Advertisements - feel thirsty? try Yu-na's Bing-su (연아빙수)!
  • Technical Training - She taught all Muhan Dojeon members, including Spins, Spirals, and three turns. The eldest, Park Myeong-su (frequently called in this programme a proper Myeong-su 고유명수) trained hard with Yu-na, although he was extremely tired.
  • Special Figure Skating Performances
    • Kim Yu-Na performed Once upon a Dream.
    • Swan Lake (later the concept was changed to Baek-suk (chicken boiled in plain water) in a Lake 백숙의 호수), performed by No Hongchul, Jeong Hyeong-don and Ha Ha.
    • Y.M.C.A performed by Yu Jae-seok, Park Myeong-su and Jeong Jun-ha.

• Please, watch your mouth - Muhan Dojeon Goes To Japan (입조심하길바래 특집-무한도전 일본 팬미팅)

The aim of this episode was to determine the truth of Jeong Jun-ha's story (he claimed that he met thousands of Japanese fans when he went to the Han-ryu Expositions in Tokyo on August 15, 2007) and Ha Ha's story (he claimed that on September 15, 2007, during the opening segment of the 'Sseokso and the city' episode that, in Japan, his popularity is almost the same as Shinhwa, a K-pop Idol group).

• • Check-points: Will the number of Jeong Jun-ha's fans reach more than 1,000? - The answer was no; however, there were roughly 200 members of his fan club in Japan (so claimed the club president), during a confirmation in a quick fan-meeting in the Ginza District.
  • All members of Muhan Dojeon travelled around the suburbs of Tokyo to find their beloved Japanese fans. They visited the streets of Akihabara (around 11:00), Ginza (at 14:00 for a quick fan-meeting) and Ueno Park (at 17:20 for an autograph signing). However, although they had performed many of their trademarks (including Hwang Jin-i dance (황진이춤) by Park Myeong-su, Geo-seong Aerobics (거성체조) by Park Myeong-su and Ha Ha, Dooly Dance (둘리춤) by Yu Jae-seok, Lewd Dance (저질댄스) by No Hongchul, Shaky Dance (진상댄스) by Jeong Hyeong-don and more), most Japanese people didn't even know them and their appearances (a few beloved fans eventually got to meet all members of Muhan Dojeon).

• Muhan Dojeon's Autumn (seasonal) Field Day (무한도전 가을운동회) - filmed at an elementary school in Paju.
  • A bargain is a bargain - Due to the recent fallout on a challenge (Short Track Relay), all members of the team 'Little Bitty' (Park Myeong-su, Yu Jae-seok, Ha Ha) eventually had their hair permed. During this scene, a beauty expert of Park Myeong-su suffered a huge difficulty, because of a few strands of his hair.
  • Game 'Blue flag & White flag' (청기백기)
    • Team races - White Team (No Hongchul, Jeong Jun-ha, Jeong Hyeong-don) got a victory (2:0).
    • Individual races - All members of Whites got their victory (3:0). Therefore, all Blue members (Park Myeong-su, Yu Jae-seok, Ha Ha) received the penalty of beating their heads against a traditional Korean drum. During this scene, Jeong Hyeong-don was upset when trying to host this game, due to the rainfall starting just after his hosting, incidentally. The others proclaimed that even the weather helps Hyeong-don's character, 'awkward comedian'.
  • Gourd-popping - Whites succeeded in popping their gourd, so they had their lunch earlier than Blues.
  • Korean Marionette performance - All members performed a traditional Korean play; however, the entire staff (except camera supervisors) were busy eating their lunch.
  • Tug-of-war Match (줄다리기, 6:6, later 6 vs 4) - They challenged against their giant-weighted staffs, but sustained a huge loss (0:3). It reflects the contents of the Rashless 1st-ever episode (on April 23, 2005, Muhan Dojeon vs. a bull)
  • Find my half (내 반쪽을 찾아라) - All challengers should run 20 meters, and tear open a balloon to find each individual mission. The one who succeeded in his mission could run a track quickly (the first challenger to complete his mission is the winner).
    • Group 1

• • • Group 2

• • • Final Round

• Madness Couples (환장의 짝꿍) - The aim of this segment was to find a relationship between each member of Muhan Dojeon and its staff. Starring:
  • Moderated by the Host-in-chief Yu Jae-seok & Shin Mi-so (신미소), Yu's fashion coordinator
  • Geo-seong (Giant Star) Park Myeong-su & Jeong Seok-kwon (정석권), Park's entertainment manager and also one of his buddies (roughly 20 years).
  • Ha Ha & Kim Ju-yeon (김주연), hard-working entertainment manager (during the previous episode, he showed his superb power on 'Tug-of-war' survival to crash the team Muhan Dojeon)
  • Jeong Jun-ha & Choi Jong-hun (최종훈), almighty coordinator (manager) of both Jun-ha and Muhan Dojeon
  • Jeong Hyeong-don & Moon Jong-seung (문종승), his former manager for 2 years
  • No Hongchul & No Seong-cheol (노성철), his elder-brother (currently obtaining a doctorate in Engineering at Yonsei Univ.)
• Job-interview of Muhan Dojeon (무한도전 신입사원 면접특집) Part 1

The members challenged an annual recruit of MBC for the seat of experienced entertainment producer (경력직 예능프로듀서), with having their (quite) well-made D.I.Y. experience which featured on the previous episodes of 69, 70, and 71. First of all, they checked their resumes, however, this process created a huge laugh for its viewers. Segments aired included Yu Jae-seok (who showed his self-confidence strongly), Park Myeong-su (who seriously threatened the MBC to pick him - otherwise he might move to other contenders such as KBS and SBS) and Ha Ha (featured his composition skills, which looked like those of an elementary school student).

• A lesson of being a Father (아빠수업 특집)

Inspired by the movie Three Men and a Baby, which host Yu Jae-seok saw and suggested as a theme. Planned based on suggestions by a viewer (Lee Sae-bom, nicknamed on the iMBC: 'uuusi'). Here is their summary of work on that day which was filmed on October 6, 2007.

• • 16:00 ~ 17:00 - All members arrive with some embarrassing moments. Ha Ha and Jeong Hyeong-don spread rumors that a baby which slept on Yu Jae-seok's living room floor was his unconfirmed son. No Hongchul arrived with a noise (that scene was to claim his Dol+I identity, accidentally).
  • 17:00 ~ 17:30 - Introduction of a baby (Im Yeh-jun 임예준, born September 23, 2006). During the introduction, Jeong Jun-ha talked about the extraordinary size of his head (called 'Helmet', more than 10 times bigger than a baby's one) and its weight (his Helmet weighed 8~9 kilos; an entire baby weighs just 9 kilos). All members tasted a Powdered milk formula which should be given to a baby.
  • 17:30 ~ 18:00 - A chaotic moment just after the baby woke up from his afternoon nap and cried when he saw the members and thought that a group of strangers were bothering him. Yu Jae-seok suffered from a big mistake by pouring boiling-hot water to reconstitute the baby formula; the correct order was to pour in warm water.
  • 18:00 ~ roughly 18:40 - Park Myeong-su succeeded in softening his character ('a son of devil') by caring warmly for the child like a dad ('father' 아버지, another famous character of his on this programme). However, he eventually let loose a fart due to his tiredness, and then all members and staff ran away to breathe fresh air (naturally, causing the baby to cry again).
  • At night - Both the members and staff of Muhan Dojeon decided to stop filming and send a message to its viewers that this challenge eventually failed, due to the child crying continuously when the members even looked at him.
• Job-interview of Muhan Dojeon (무한도전 신입사원 면접특집) Part 2

• Jun-Hines Ward Special (준-하인스 워드 특집)

The aim of this episode was to invite a top American Football player to film a sporting segment; however, due to his recent injury, his entire visit to South Korea had been postponed. Jeong Jun-ha, a member of Muhan Dojeon whose body type is fairly similar to Hines Ward, eventually disguised himself as Ward and challenged some of the segments with other Muhan Dojeon members which has been proposed.

• Muhan Dojeon's Captain Planet

The aim of this episode is to call all members of Muhan Dojeon to alert the severe dangers on Earth such as Global warming, Environmental disruptions, Natural disasters, and Extra-terrestrials.

• 'Renewable Energy' special
  • Intro-joke - Muhan Dojeon's routine on their holiday (clay-animated cartoon film)
  • Operating a Hair dryer by making their own electricity riding bicycles - 40 people from its high-profile staff eventually succeeded in styling their members' hair.
  • The 2nd shop of Coffee Prince - The name of this segment was a parody of 'Coffee Prince', a top-rated television drama on MBC. 2 people (members) should serve at their self-made (prepared for an entire month) vending machine located at the lobby of MBC. Generally, the automatically operated electronic vending machine takes only 13 seconds to prepare a cup of coffee; however, they delivered coffee in about a minute to their customers.
  • Car Racing with Manpower - Team 'Piggy' (Jeong Jun-ha & Jeong Hyeong-don) won this ridiculous 30-minute struggling race. More details soon.
