'Problem Child in House' singer Kim Jong-kook lit a green light for plans for a second child after earning the title "sperm king."
On the 18th broadcast of KBS 2TV Problem Child in House, forensic doctor Professor Yoo Seong-ho appeared.
Professor Yoo, who usually declines entertainment grants, said, "I came because there were people I wanted to meet," and mentioned comedians Song Eun-i and Kim Sook. Yoo confessed that he enjoyed listening to the podcast "Secret Guarantee," which the two started when they were briefly hesitant, drawing attention.
Professor Yoo, who doesn't watch TV programs much, said he truly believed the marriage rumors about Kim Sook and Koo Bon-seung, causing laughter. He also mentioned Kim Jong-kook, who is soon to be married.
Professor Yoo referred to Kim Jong-kook earning the title "sperm king" with a sperm count exceeding 200 million per 1ml, and elicited another burst of laughter by saying, "Wow, that's amazing."
