Sam says, "Oh, I hear that the new Dr Who has reproductive organs on the inside, not the outside."
Daniel is only half-listening. "The TARDIS is much bigger on the inside than the outside," he says.
Jack tries to make sense of this conversation. He can't. Clearly, he needs more coffee. Somehow, this comes out as, "Do they have coffee on board the TARDIS?"
"Just because she's a woman, that doesn't mean she has to make the coffee!" Sam is mildly outraged. Daniel is confused: who was talking about women? He certainly wasn't.
Jack goes to find coffee.
