On the January 6th episode of 'Infinity Challenge', Jo Se Ho invited Lee Dong Wook, who decided to put the comedian on blast. Yoo Jae Suk asked, "Did you really come because of Se Ho," and the actor responded, "It's not like that. I wanted to let people know what I was doing. I'm not on any TV shows right now."

Lee Dong Wook continued, "It's been a year since 'Goblin' ended. I thought viewers would be curious what I have been up to. I'm doing well."

When asked what kind of friend Jo Se Ho is, Lee Dong Wook responded, "He gained a lot of weight recently. I've known him for 3-4 years, and he's fatter than ever before. He also takes showers quickly. He takes 10 minutes at the most. I think he takes 2 minutes on average. I don't think he washes himself very thoroughly."

Jo Se Ho then explained, "I don't use soap often."
