Professor Robert Kelly and his family became a viral sensation through a BBC interview in which the kids interrupted his online interview. He featured as a guest on this particular episode as he had special connection and relationship with Sam Hammington. Sam Hammington said, "When the BBC interview went viral, I initially contacted him personally via SNS. I thought he and I were both in a relatable environment; a foreigner living in Korea who has kids just like me. I thought we could converse well in that aspect."

Sam Hammington was excited to sit on the same chair Professor Robert Kelly sat in when the viral interview took place. He called his mom to brag but she wasn't able to identify the location until Professor Robert Kelly showed up on the screen in which Sam's mother screamed, "Oh my god!' to cause laughter.

The professor revealed his thought process at the time when he and his family went viral, "I thought my broadcasting career was over. After, I received over a thousand media contacts including the 'Ellen DeGeneres Show'...". He also stated that the head of CNN also contacted him. 

When asked why he decided to come on 'Superman is Back,' he replied, "This show is very family-friendly and to be honest I was scared at first but now I'm starting to feel more comfortable."
