The Worm: 'Allo.
Sarah: Did you say... hello?
The Worm: No, I said "'allo," but that's close enough.
Sarah: Oh... you're a worm, aren't you?
The Worm: Yeah, that's right.
Sarah: You don't by any chance know the way through this labyrinth, do you?
The Worm: Who, me? No, I'm just a worm. Say, come inside, and meet the missus.
