The following quote is taken from the serial Spearhead from Space. It is the first appearance of the Third Doctor.
The Doctor: My goodness, no. Don’t you realise that when I was stranded on this little planet of yours, I had nothing but these clothes that I Oh, my goodness!
Liz: What is it, Doctor?
The Doctor: Well, I’ve just realised. I don’t even own these. I borrowed them from the hospital. And there’s that car, too. Yes, you know, I took to that car. It had character.
Doctor: Must it? Yes, yes, I suppose it must. Still, there’s no reason why you couldn’t find me something similar, is there? I mean, it could persuade me to stay, you know.
Brigadier: Oh, very well.
Doctor: Good. When can we go and choose it?
Brigadier: Not yet. I must arrange for a full set of papers first. By the way, I’ve just realised. I don’t even know your name.
Doctor: Smith. Doctor John Smith.
