Quaid-e-Azam University Professor Zafar Jaspal on Saturday gave his son 'instructional gestures' for entering a room where he was giving a live interview to an international news outlet.Jaspal was invited to speak to al Jazeera as an expert on the terrorist attack on Friday's attack on Chinese consulate in Karachi.In the footage, Jaspal's son could be seen appearing in the background. Upon noticing his son's presence, the professor silently gestured at him to leave the room, so that the interview is not interrupted.The video soon went viral, with Twitter users drawing parallels between the media talk and a video last year of children crashing their father’s interview with the BBC.In the interview, Professor Robert Kelly was speaking to the channel via Skype on the issue of South Korean politics. As he answered a question, a young girl wearing glasses could be seen strutting into the room.The moderator pointed out to the professor that one of his children had walked into the room. As Professor Kelly tried to push his child out from the camera frame, the younger sibling tottered into the room as well in a baby walker.
