CLYDE: How many Doctors did you know?

JO: Oh, more than most. Three, once. Well, no, three all at once, once. Well, no, actually, wait a minute, two and a bit.

CLYDE: Which bit?

CLYDE: She's so busy, you know? And what she does is important. What do I do? I just... I write daft comic book stories.

JO: Oh, stories are important, Clyde. We're made of stories, and you're missing the most important one of all. Mine wasn't the Doctor, it was Cliff. My darling Clyde, don't miss your story with Rani.

CLYDE: I don't know how. You know, I... I've just always been the joker.

JO: Then tell her in a joke. Oh, but tell her. Our time together, that's the most precious thing we have. Don't waste it.
