OOC - What should we ask Chris Barrie?

Sorry to boast, but I've just been talking to a journalist who's doing an
article in the magazine "Retro Fusion", available in Gamestation stores in the
UK.
The above sentence had a reason, other than for my ego! The journalist is next
week interviewing Chris Barrie, and has asked if there is one question that I'd
like to ask him. Other than "Will you join Blue Dwarf?" I'm finding it difficult
thinking of the best question, so I thought I'd open it up for discussion.
So what question should we ask him?
I've created a thread in the forum (www.bluedwarf.co.uk/forum) inside "random
chat" for your replies. Don't reply here or it will get in the way of the story
