A BBC News show went off the rails this morning - in a good way - when two unexpected young guests crashed their dad's serious commentary on South Korea.

Robert Kelly, professor of political science at Pusan National University, was on the BBC show to talk about the removal from office of South Korean President Park Geun-Hye.

As Kelly spoke about the president's impeachment, his two adorable children burst through the door to his home office where he was filming.

Kelly gamely tried to stay focused as a woman frantically burst through the door and desperately herded the noisy little ones away.

Kelly couldn't help but laugh and offer his apologies. 

"Robert, many thanks," the host laughed at the end of the segment.

"That's a first time for everything. I think you've got some children who need you!"
