He was a guest on the recent episode of KBS 2TV's 'Hello'. During the introduction, Lee Young Ja claimed, "The more I see him, the more I think MC GREE looks so much like Kim Gu Ra's son!" MC GREE was confused at the comment as he is Kim Gu Ra's son, but she continued, "I keep wanting to ask if your father is doing well."

After a confused moment of silence, MC GREE asked, "Are you making a joke," to which she replied, "No, I'm serious." He answered, "My father is Kim Gu Ra." She was flabbergasted by this and said, "Your father is Kim Gu Ra?" The other MCs, realizing she actually had no idea, laughed and said, "What are you doing?" 

The pair managed to sort everything out, and she explained she hadn't seen him since he was very little (and still working under the name Kim Dong Hyun). The moment of confusion provided the studio with a round of laughter.
