The BBC news interview that inspired this cartoon was one of the funniest things I had seen for a long time. I think most people who have seen the clip (and very few haven't) would agree with that. But its popularity wasn't just down to how funny it was; At a moment in history defined by how divided we are, it reminded us that we're all similarly imperfect, unscripted human beings. One of my favourite things about the clip is the way in which Professor Kelly tries so desperately to maintain his professional conduct during the interruption, but eventually can't help but succumb to the hilarity of the situation. We all spend much of our adult lives pretending to be more serious and important than we actually are. And that's truer of our politicians than anyone else. Professor Kelly's children reminded all of us to lighten up a bit. The mission statement of a political cartoonist needn't be any more complicated than that.
