'BBC Dad' is back on TV (but this time he locked the office door)

/ Source: TODAY

"BBC Dad" is back doing serious interviews in his office. Unfortunately for the rest of us, he remembered to lock the door this time.

Robert Kelly, the professor at a South Korean university whose children adorably crashed a live interview with the BBC last week, appeared on CNN International Wednesday to discuss a failed North Korean missile launch.

Kelly couldn't resist a little dad humor before his appearance.

It marked Kelly's first news-related interview since his 4-year-old daughter, Marion, and 8-month-old son, James, barged into his home office during a webcam interview he was giving to the BBC about the impeachment of South Korean President Park Geun-hye.

Kelly tried to keep it together while his wife, Kim Jung-A scrambled into the room and corralled the children before yanking them out of there.

"My real life punched through the fake cover I had created on television," he told reporters at a press conference last week. "This is the kind of thing a lot of working parents can relate to."

With her confident, "hippity-hoppity" strut, Marion was the clear star of the show. She again charmed everyone at the press conference on March 16 while sucking a lollipop in her pink glasses and fashionable outfit.

As Kelly spoke to CNN on Wednesday, there was a sad realization - Marion is not coming through that door. All good things must come to an end.
