During the April 14th broadcast of JTBC's 'Knowing Brothers', comedians Yoo Min Sang and Moon Se Yoon appeared as guests. While conversing, Yoo Min Sang abruptly asked Seo Jang Hoon, "How much do you weight? If I beat Seo Jang Hoon, I'm the heaviest celebrity in Korea."

He then revealed his weight, "I weigh over 130kg (~287lbs)." Seo Jang Hoon replied, "I've lost weight recently so I don't weigh that much." After hearing this, the comedian proudly said, "Then I'm in first place. Kim Joon Hyun is in the 120kgs."
