Matt Smith being adorable. In order to be the doctor: Use the word Wellllll. Combined with the Matt Smith effect (see photo above). Run around yelling DALEKS. Your Doctor lesson for beginners is complete.
This really does break my heart, cause you tend to forget that the Doctor was a dad once. And then you realized that he had a wife and kids, and he destroyed Gallifrey. Doctor Who punctures your heart, people.
