It appears that the production staff decided to surprise the show's cast members with Jung's return. Kim even mentioned how he and his fellow cast members initially thought that the singer will not be able to rejoin the show. He stated, "We thought Jung Joon Young was going somewhere else."

In other news, Cha Tae Hyun was able to convince his celebrity friend Jo In Sung to make a guest appearance in the said KBS variety program. However, the actor's potential cameo is linked to the box-office performance of Jo's latest movie "The King."

In a recent V app broadcast, as cited by Xports News, Cha challenged the actor to dunk himself in the water while on the KBS show if the said movie reached ticket sales of 8 million. Jo may have expressed his hesitation over the said challenge given the cold winter season, but eventually accepted Cha's request.
