On November 9th's episode of MBC's�'Golden Fishery - Radio Star', MC Yoon Jong Shin shared a hilarious story about his eldest son, Ra-Ik. He began, "I guess I ask him the same thing every single day. All throughout the week, all I ask is, 'What did you learn at pre-school today?' and one day my five year old son replied, 'What do you think we did...'." Yoon Jong Shin continued,�'What do you think we did? It's the same old -- we folded construction paper and other stuff like that." MC Kyuhyun remarked that Ra-Ik is extremely mature for a five year old, causing laughter to continue rolling on set.
