John Egbert! Rose Lalonde! Were you still going to bring your friends around for a tea party in the TARDIS? Not that you have to bring them around, we can always take the TARDIS to them instead.  However.  I'm afraid we'll have to do it quite soon.  Before long, she's not going to be fit for human habitation, so unfortunately this has become a limited-time offer.  It has to be this week.
