In an interview with the Wall Street Journal, political science professor Robert E Kelly admitted the BBC clip was a "comedy of errors" from start to finish. And as we all now know, the miss would lead to every working parent's worst nightmare.
"She was in a hippity-hoppity mood that day because of the school party", Kelly said, explaining that it was her fourth birthday.
Following the interview, some suggested Mrs Kim was in fact the children's nanny, leading to discussions about how Asian woman are perceived.
As the interview began, the couple's 4-year-old daughter Marion jumped up and down at the sight of her father on the screen.
The video quickly became a viral hit, so much so, that they family had to disable social media notifications and set aside numerous requests for comments.
Despite the comical interruption, Kelly was able to finish the interview. But they didn't. And then I saw the door was open. "We've watched it multiple times since and our families have watched it as well - it's pretty hysterical".
Ms Kim had only noticed the children had left her side when she saw them on the television. Or perhaps she is a regular kid in a regular family acting like a goofball because that's what little kids so.

Gold Coast will host in 2018 but she said it was unlikely the same city would go back-to-back. Durban 2022 would have been the first staging of the Commonwealth Games in Africa.
"Yes, I was mortified, but I also want my kids to feel comfortable coming to me", he said.
Robert's wife, Kim Jung-A is then seen darting in to retrieve her children from the interview, as the academic repeatedly apologises to the interviewer, James Menedez.
The video has been viewed on the BBC Facebook more than 84 million times and covered by countless news agencies around the globe. "I saw the door open", Kim recalled.
The inside story has been revealed about the sweetest viral video ever, in which a young girl gate-crashed her dad's live and very serious interview with BBC News.
"My wife did a great job cleaning up a really unanticipated situation as best she possibly could.it was amusing", he told The Wall Street Journal. Many people on Twitter agreed.
Kelly managed to maintain his composure as he politely apologized to the BBC anchor for the unexpected video-bomb.
