On this week's 'My Ugly Duckling', Song Ji Hyo will be joining the mothers and the MCs in the studio to observe the single lifestyles of Kim Gun Mo, Park Soo Hong, Tony An, Kim Jong Kook, and more. During her introduction, Song Ji Hyo appealed to the mothers by saying that she is great at housework. The mothers then each laid out various reasons why they would be great mothers-in-law, to which Kim Jong Kook's mother chimed in with, "Ji Hyo was originally my daughter-in-law!"
