Everything has to be intrinsic plot-wise in the same way, to use the Linda Williams analogy but to move it on a bit, as musicals - in old musicals, like in an old Cole Porter musical, you get the action, then they do a song, which reflects a moment - everything stops while that is being sung - and then you restart. These days in most musicals, the plot keeps moving through the song. I think it would be nice if someone constructed some pornography where the sex continues to propel you through the story.

The Doctor: Sorry, do you have a name? Idris: Seven hundred years and finally he asks. The Doctor: But what do I call you? Idris: I think you call me... Sexy? The Doctor: [embarrassed] Only when we're alone. Idris: We are alone. The Doctor: Oh. Come on then, Sexy.
