You know, there's a fairly common recurring prompt of "Mary Poppins is a Time Lady", because of the carpetbag, but I recently concluded that Mary Poppins is actually more like Chrestomanci. For reasons.

So, by a subtle and complicated process known as "violently wresting the topic back to Doctor Who" (yes I'm in a weird mood), I should like to see Chrestomanci meet the Doctor. Any Doctor. One, for instance; the amount of name-fluffing alone would probably set new records. O_O ;-)
