Dr Moon: Shall we go down to the river?
Cut: they are by the river.
Donna (confused) You said “river” and suddenly we’re feeding ducks!
Amy: It’s a duck pond.
The Doctor: Why aren’t there any ducks?
Amy: I don’t know. There’s never any ducks.
The Doctor:Then how do you know it’s a duck pond?
Amy: It just is. Is it important, the duck pond?
The Doctor: I don’t know. Why would I know?
Maybe it’s connected.
Or maybe I should find something more useful to do.
