During the February 11 installment of the JTBC program, Lee Hyori and Lee Sang Soon burst out into laughter with a little help from Girls' Generation's YoonA. While they were looking at all the pictures of their guests, YoonA offered to take a picture of the married couple for them. While doing so, however, YoonA had a little fun as she swapped Lee Hyori and Lee Sang Soon's face through an app. All three couldn't stop laughing and even showed the picture to their guests

Lee Hyori joked, "What're we going to do if our daughter looks like this in the future? Imagine her being our oldest kid."
