The show might be called Doctor Who, but the lead character isn’t. He (or she) is the Doctor, even if the actor playing the part has been credited otherwise. However, in the 1966 story The War Machines several characters refer to him as “Doctor Who”, which upsets the fanboys no end. Third Doctor Jon Pertwee was highly critical of K9, saying he was twee and unnecessary for a genius like the Doctor. Happy Birthday Doctor!
