The lack of response from VJs, when Song Il Kook's triplets would ask them questions during 'Superman is Back', has been bringing laughs as well as curiosity about why the VJs do not respond.

PD Kang Bong Kyu told OSEN, "Because their main goal is to show how the fathers and children spend their time together, the VJs don't respond to the children's questions..." He pointed out the adorable moments of Min Guk going up to the cameraman who wasn't covered up as usual, and asking, "Ahjusshi, what are you doing?", as well as another time when Min Guk noticed a dead fly on the window sill and asked the cameraman what it was multiple times. With no response from the VJ, Min Guk went closer to the cameraman continuing to ask, which finally awarded him a response of "Bug," from the VJ.

The PD explained, "At the time, he tried to send Min Guk off with a hand gesture but it didn't work too well. Upon watching that scene while monitoring, all of us got a big laugh."

He also revealed the staff's fondness for the 'Superman' kids and the families, by adding, "A PD and writer get assigned a fixed family. Because Sarang, Haru, and the twins have already been filming for over a year, the children and producers have established a strong bond. The children call the PD and writer 'aunt,' 'uncle,' or 'ahjusshi'... During breaks in between filming, sometimes they ask to be held. When the father can't care for the children by himself, the staff also watch over the children."
