During the January 4 episode of KBS2's 'Happy Together 3', Yoo Jae Suk said, "I went to my son Ji Ho's field day. My experience on variety shows was a lot of help. I shared tips on tug of war and more (to others)."

However, Yoo Jae Suk revealed his son wasn't too pleased with his active participation. The MC continued, "My son was embarrassed by me. (Because) I overreacted."
