The Doctor: I dunno. Anywhere else in the universe I might worry about but Ney York: it's what this city's good at. Give me your tired, your poor, your vulnerable masses and even the odd pig-slave-Dalek-human-hybrid too.
Martha: (laughs) The pig and the showgirl!
The Doctor: The pig and the showgirl.
Martha: Just proves it I suppose; there's someone for everyone
The Doctor: Maybe.
