Knowing Bros

Format

Brother School

• Entrance Application – a segment where a cast member reads the application forms the guests filled beforehand and other cast members comment on them. A highlight of this segment is the guests' preference for which cast members they would like or would not like to sit next to. The guests typically show their strengths and/or weaknesses through this segment.
• Guess About Me – a segment where the guests have prepared several questions related to themselves. Some of the questions are vague or extremely private and concern something the guests have never revealed to the public. In another format, idol groups with more than 5 members that are visiting for the first time will have their names covered, and as Heechul reveals a fact about the member, the group members would try to confuse the cast.

• Second Period – a segment that usually comes after the permanent segments and varies between guests. In most cases, the guests have made suggestions on the activities for this segment. Examples include counseling sessions, art class, and physical education class.
• Let's Play – a short segment where the guests challenge the cast members to a game which the former is confident in winning, usually by unorthodox means such as on-the-spot rules. The segment usually ends with a challenge where the guest needs to defeat every cast member consecutively.
• Three No's – a segment that revolves around an ad-libbed skit where the cast members and guests are not given any dialogue or definite storyline. They can only rely on the overall theme of the particular week's skit and their own comedic timing.
• Music Class – a segment where the guests have created a list of songs with a specific theme of their preference. The segment focuses on the cast members' effort in guessing all of them in the correct order. There are often hints such as release date, characteristics, or "Jonghyun's game" as it was introduced in ep. 29 by the late Jonghyun, wherein the beginning syllable/note of a verse is given with its rhythm to help the members guess the song name.
• Lee Sang-min Time – formally introduced in ep. 56 and formerly called Choose Your Type, is a short segment wherein the guests are briefed by Lee Sang-min to choose any of the cast members as their ideal partner. The specifications are that all members are "equal" in terms of legal, socioeconomic, & civil statuses; and that the choice is based only on their physical appearances and personalities.
• Dancestagram – formally introduced in ep. 57 by Chanmi. In Psy's episode it became a segment where the PD plays the beginning syllable/note of a song and they have to guess the title, lyrics, and dance move.
• 99 Seconds Teamwork Competition – a segment that is often used when a large group of people are guests on the program, such as idol groups. The segment varies each episode in terms of missions, but the members and guests must complete them within 99 seconds. If a team manages to complete them in time, the other team is given a chance to produce a better time record.
• Classical Culture Class - a segment all about pop culture references to forgotten decades.
• Imagination Time - a segment which starts with a warm-up, like drawing something from shapes, and guessing lip-synced words. The highlight of "Imagination Time" is Guess the Drama Line. The members and guests have to guess what the next line of the scene from a drama shown to them is.
• Knowing Lunch - a segment that comes in between the Entrance Application segment and the Guess About Me segment. The members and guests answer questions given by the production team and if they are guessed correctly they can eat one of the numerous side dishes selected, other than white rice and light soy sauce that was already provided beforehand.
• * A variation of this is that each member must ask a question of their choice, but only the specified amount of people can guess correctly.
• * There is also one question where a specially requested item is covered under a cloche. The way to gain the food item varies in each episode.
• XXX Scholarship Quiz - a second half segment in Brother School, where Shindong enters the classroom and hosts the quiz. The members and guests form pairs and play the games to enjoy the food. Typically this consists of two segments:
• * Consonants Charades: When two consonants are given, whichever pair hits the buzzer first gets to answer. To answer, one of the pair has to express the word without saying what the word is, and the other has to guess the word.
• * Mix Music Quiz: Shindong sings the lyrics to song "B" in the melody of song "A". One of the pair has to answer song "A" and its singer, and the other of the pair has to answer song "B" and its singer.
• Job Consultation Room - an official corner of the show after the Brother School segment for the episode has ended. Jang Sung-kyu, Shindong and Jeong Se-woon would let guests, as Variety Job Lookers, to prove their variety skills to the three.
• After School Activities - the cast members each learn something unique that is not done during the "lesson". This segment is shown on both TV and YouTube, after the end of a Knowing Bros episode.
