Sarah Jane: All the time! (Laughs) Does he still stroke bits of the Tardis?

Rose: (giggles) Yes, he does! I'm like, "Do you two want to be alone?"

Doctor: How's it going? (The girls burst out hysterically laughing) What? Listen, I need to figure out what's programmed inside these. (The girls are still laughing, Rose points at him as he's getting annoyed) What? Stop it!
