Knowing Bros (), also known as Men on a Mission or Ask Us Anything, is a South Korean television entertainment program produced by SM C&C that premiered on December 5, 2015, and currently airs on Saturdays at JTBC. Although the show has taken on different formats in some episodes, the program features a high school classroom setting with the fixed cast – the titular "brothers" – acting as same-aged students. Guests arrive posing as visiting students from another school and are interviewed by the cast in a talk show segment; the program's second half usually features a variety segment, with the cast and guests taking of activities such as games, talent show, or improvisational acting.
Knowing Bros
A notable aspect of the show is the usage of the banmal (; "informal language") manner of speech used by everyone regardless of their age or seniority, thus disregarding the Korean language's strict seniority rules with spoken language and the - hierarchy in the Korean entertainment industry. The informal speech and casual setting also encourages the guests and cast to interact with each other as schoolmates often do, leading them to be comfortable enough to tease one another.
There are at least two permanent segments, which have defined the Brother School format:
