OK, this is one of those nitpicks I see a lot that is not strictly accurate. I could see McGee only having watched classic Who, and here's the thing: while he never called himself "Doctor Who" on screen, in other ways he was referred to as "Doctor Who", such as in the credits. So it's not necessarily always just wrong to refer to the character by that name.

Still skipping NCIS for V, and still enjoying NCIS:LA.
