Steven Moffat in his interview at Paris ComicCon
Interviewer: If you had a TARDIS, when and where would you go?
Moffat: Oh, I dunno. Everyone else in the world has a better answer than me right now. Never ask a happy man where he wants to go, I just don't really want to go anywhere.
Moffat: Maybe I would take some Sherlock DVDs back to Sir Arthur Conan Doyle and see what he thinks.
Moffat: He'd probably punch me.
