"I thought there was an anguished moment of pure beauty in The Office. It was between Tim and Dawn, and there were kisses being sold for Comic Relief, and he gives her a pound. Of course they’re both terribly in love, but they haven’t admitted it. And she says “Well you have to have your kiss now.” and so they have to kiss. There’s this brief incandescent kiss. It’s the sexiest thing you’ve ever seen, and they’re almost physically stunned by it. But it’s so real and so content that I think today I’m nominating that as my favourite bit of TV drama, even though it’s in a comedy."
