He said the dance needed that look, and his castmates remembered his earlier stadium performance. On KBS2's 2 Days & 1 Night Season 4 on October 25, Lee Joon began removing his jacket before a dance-and-quiz challenge. Kim Jong-min teased him for always wanting to take his clothes off.
What was the game?
Six entertainers in Seosan, South Korea, were competing for a ten-dish barbecue dinner. They had to identify answers in photos while imitating a robotic dance. Producer Seo Yu-jin's unexpectedly skilled moves and completely straight face made the cast laugh. Former dancer Kim Jong-min and former MBLAQ idol Lee Joon praised her technique.
Where did the sleeveless look originate?
On April 22, Lee Joon threw a ceremonial pitch at an LG Twins–Hanwha Eagles baseball game in Seoul. He then joined the cheering squad for the YouTube workplace series Workman. Wearing a white sleeveless top, he danced to YENA's cheerful “Catch Catch” with almost comically intense concentration. YENA reportedly joked that he had stolen her song. Workman's longer episode appeared on May 15 at 6 p.m. Korean time. The reported 10 million views referred to combined short-video views, not necessarily the long episode alone.
Why was October's callback funny?
The goal was to win dinner by answering correctly, but Lee Joon focused on his costume first. Kim Jong-min, DinDin and Moon Se-yoon piled on. Everyone else was looking for the answer; he was preparing for a stage performance.
Conclusion
The shirt recalled his unusually serious cheerleading routine. April's stadium and October's broadcast were separate events. This account is based on dated reporting, not a claim to have watched the full October episode or proof of a worldwide trend.
