Every week they report on the world in a really original way. Their recent shows have been all about social media and internet trolling – and it is just wonderful. They make you realise how strange and absurd that world is. But the show I would nominate is the three-parter they did called Imaginationland. It is about how terrorists take over all of our imaginations – and then our imaginations run out of control with dark horror. So the US government decide to nuke our imaginations. But Kyle from South Park confronts the government and makes an epic speech about how what we imagine inside our heads is more real, and has had more effect on the world throughout history than us as just physical beings.

The whole story is a wonderful attack on the narrow rational utilitarianism of our age that both left and right have bought into. It’s saying: you can make the world anything you want it to be. At its heart, South Park has a touching faith in human beings. That despite their absurdities and flaws, people have the capacity to create a better world. In our conservative times that is the most radical message of all.
