"No, Not the Mind Probe!!?!"

So, I was taking advantage of my day off work to...watch repeats on daytime telly. You know how it is. Anyway, I was watching one of the David Suchet Poirots, and Paul McGann was in it, playing a doctor. And everyone else spent the whole story calling him "Doctor" all the time. Well, it tickled me, anyway.

Now I have this mental image of Chief Inspector Japp ineptly trying to interrogate Eight for some reason...
