Over the weekend you may have encountered this clip of political scientist Dr. Robert Kelly's video interview with the BBC. Dr. Kelly, reporting from South Korea on president Park Guen-hye, is interrupted by his two fantastic children - a young girl in a Wes Anderson-yellow jumper who dances into the frame as though she knows she is on live television and a baby in a roller who slowly infiltrates the scene after her just to, you know, have a check up on what's going on. 

Dr. Kelly is clearly flustered by the intrusion and this only worsens after the bull in a china shop efforts of the Mother to round up her galavanting children. I am unashamed to admit that I have watched this video at least 20 times and each time something different has made me laugh. 

The roller-baby emerging just as Dr.Kelly is trying to shoo his other child away.

The Mother stampeding in at approximately 400mph once she realises what has happened.

The carefully placed books on the bed going flying.

The final outstretched limb appearing to close the door at the end.

Perhaps naively, only after watching it a few times did it dawn on me the reason for Dr.Kelly's response. He remains, quite oddly, glued to his seat throughout. He doesn't even swivel around to watch the action unfold as yellow-jumper girl clings onto the carpet for dear life as she is dragged away from her own stardom. 

Dr. Kelly is absolutely terrified to move, even an inch, because he is sat in his pants. He knows that tie he spent 20 minutes getting right and that crisp, ironed shirt are no longer fooling anyone. He knows that we know. 

He's not embarrassed because of his children - they are adorable - it's his Incredible Hulk boxers and odd socks that are causing the pained grimace on his face. 

The morale of the story?

Moments of spontaneity like this should be cherished. They are heartwarming and sincere in a world in which those adjectives are becoming increasingly uncommon.

Oh, and always wear trousers. Even for a video interview.
