Robert Kelly, his wife Kim Jung-A and their kids speak to the Wall Street Journal

*Robert Kelly sat down for another Skype interview, this time with his two young children in his arms instead of wreaking havoc behind him during a live TV interview.

The university professor from Busan, South Korea went viral last week when his children wandered into a bedroom where he was being interviewed via Skype by BBC News.

The Wall Street Journal got Kelly, his wife Kim Jung-A and their kids on camera to discuss how it happened.

“He usually locks the door,” Kim said. “Most of the time they come back to me after they find the locked door. But they didn’t. And then I saw the door was open. It was chaos for me.”

“We said to each other, ‘Wow, what just happened?’” said Kelly, who blames himself for not locking the door.

“I made this minor mistake that turned my family into YouTube stars. It’s pretty ridiculous.”

The couple said they spent most of Saturday trying to decide how to handle the sudden onslaught of attention. Offers from major U.S. TV networks and media came flooding in. Some journalists even tracked down Kelly’s parents in the east side of Cleveland to ask them about it.

“We stonewalled because we didn’t know what to do,” Kelly said.
