Stray Kids on Knowing Bros: Episode 451

September 21, 2024 · all eight members
Quick answerStray Kids Knowing Bros episode: 451

Stray Kids appeared on Knowing Bros episode 451, aired September 21, 2024 on JTBC. It was the group’s first full-group visit to the show.

Stray Kids’ first Knowing Bros episode aired on September 21, 2024, during the busy “ATE” era, with all eight members as guests. After the usual classroom introductions, the episode moved outdoors: the hosts and members split into four teams of four for games and missions. One moment fans love comes when HAN falls during a game and turns to I.N in embarrassment. Back in the classroom, Seo Jang-hoon decided he was the group’s “guardian,” which led to the clip “What did you do to our HAN?”

The episode also has pre-debut stories — HAN’s jungle trip in Malaysia and Bang Chan getting teased as the “boomer” of the group — and a medley of hits from “S-Class” to “Chk Chk Boom.” If you search “Stray Kids Knowing Bros eng sub,” the clips below are the official English-subtitled versions from JTBC.

What Is SKZ CODE?

Stray Kids’ own variety show

SKZ CODE is Stray Kids’ in-house variety series, released on their official YouTube channel since 2021. Each episode — often a two-part arc — drops one concept on the members: a game, a challenge, a roleplay or a trip. Because it is free and subtitled, it is the easiest way to keep watching Stray Kids after you finish Knowing Bros.
