Trivia

 * His first words as The Doctor keep to the modern tradition of new Doctor's commenting on their bodies (e.g. the Tenth Doctor's first words were "New teeth. That's weird" and the Eleventh Doctor's first words were "Legs. I've still got legs."). The Twelfth Doctor first words were "Kidneys! I've got new kidneys!".
