Really, Charles? A strange man appears in a pub, drinking beer and spitting it on the floor. There's a big blue police box outside, that I'm going to get inside of and leave after this, and I come bearing psychic paper, claiming to be the Doctor of everything, and you just now realize that I'm not human. [The Doctor feels like he accomplished something]
You're absolutely correct. I'm just a mad man with a box. Or... A time lord, if you prefer.
