Ace: Pass the sugar.

Hex: That stuff will kill ya.

Ace: On the list of things in this universe that are going to kill me, sugar is a long way down.

Hex: McShane!

Ace: Try to stay calm, Hex. You'll find the initial open-mouthed shock fades after an hour or so.

Hex: It will?

Ace: Oh, yeah. It's replaced by an uncomfortable nagging sense of the uncanny, which never quite goes away, but that's a lot easier to cope with in the long run than the slacked-mouth gibbering.

Hex: Is this some kind of joke?

Doctor: In the unfathomably cosmic sense, most certainly.

DOCTOR: OK. Hold on to your hat.

HEX: I haven't got one.

DOCTOR: Then hold on to mine.
