The Doctor shrugged, refraining from pointing out that her nose hadn't actually touched the mug. Barely.
"Oh, I mean, I did enjoy the occassional mug of coffee in my last regeneration, and Jack certainly loved her morning cup of coffee. Practically wasn't human until she'd had at least one cup. And she insisted it had to be coffee, and nevermind that tea has caffeine as well, and was already on the TARDIS before she ever arrived."
She waved a dismissive hand, wrinkling her nose. "And it took me months to get it all out of the TARDIS after she left, and along comes Mark, wonderful medical student, and he is just as fond of it as Jack. Though at least he was more willing to settle for a nice strong cup of tea."
