James Corden accidentally kept Instagram Live running Tuesday, broadcasting a meltdown to 50 million viewers after a 12-year-old in Seoul, “KnifeMaster2013,” knifed his Call of Duty squad into oblivion. Witnesses described a “tea-kettle shriek of pure rage” as the former host went from cheerful banter to accusing the child of “Korean super-soldier training.” Gaming analyst Rebecca Torres said the kid looked like a “digital ninja,” teleporting while Corden’s controller learned to fly. Unaware he was still live, Corden paced and issued a formal challenge. “Right, you little legend—real world,” he bellowed. “Times Square, tomorrow at noon! Bring your best kitchen knife, because I’m bringing my carving skills from the old country!” Chat spiraled. Park replied with a victory dance emote, then logged off. Corden googled contact info and international foam-sword shipping like a man planning Comic-Con. His team later called it “playful hyperbole,” but #CordensRevenge trended anyway. Park, via his brother, advised Corden to “try the tutorial.” Times Square vendors began printing “Duel Zone” tees before lunch.
