The Doctor and Rose Tyler in “Rise of the Cybermen”

If you want to know what's going on, work in the kitchen.

According to Lucy, that man over there...

Who is Lucy?

She's carrying the salmon pinwheels. [nods towards a waitress on the other side of the room]

Oh, that's Lucy, isn't it?

Yeah. Lucy says that that is the President of Great Britain.

What, there's a "President", not a "Prime Minister"?

Seems so.

Or maybe Lucy's just a bit thick.
