Professor Robert Kelly, from the department of political science at Pusan National University, was discussing the impeachment of South Korea's president Park Geun-hye on BBC World News during the 11am bulletin.
But as he talked to presenter James Menendez about President Park being ousted from power, a child burst into the room unannounced, and proceeded to dance behind him.
Prof Kelly managed to keep a straight face and continued to discuss whether the decision would affect South Korea's relationship with North Korea, only for an infant in a baby walker to arrive, bouncing into the room.
At this point, Prof Kelly seemed unable to answer the questions with the chaos unfolding behind him.
A split second later, a woman could be seen sliding into the room to frantically gather the children and pull them out.
As the children were heard wailing in the background, Prof Kelly smiled, apologised and continued his segment.
The clip lit up social media, prompting many users to watch it over and over again.
One Twitter user wrote: "Spit out my coffee when the toddler rolled in. I can relate. Whenever I'm interviewing someone on the phone, my dogs go nuts."
Former shadow foreign secretary Douglas Alexander wrote: "This clip made me laugh out loud. #Therebutthegraceofgod"
