This sketch will also contain jokes. And make no mistake: some of those jokes will be a bit weird. Especially the one that ends with me saying to Ed Miliband: “You keep your shirt on – and I’ll keep the lights on!” That one will just sound like a very odd chat-up line. There will also be a joke at the expense of Labour’s education spokesman Stephen Twigg where I misread the autocue and mess it up completely. Never mind. I’ll soldier on.
