(Sir Arthur Treadley has stormed in and begun yelling at Holmes over the bad advice he got last week)
Holmes: Yes, why don't you introduce yourself.
Sir Arthur Treadley: Introduce? Mr. Holmes, what tomfoolery is this now?
Holmes: You know my name, Sir. I wish I were equally informed as to yours.
Sir Arthur Treadley: Do you mean to sit there and pretend you don't know who I am?
Holmes: I not only do not know who you are, Sir, but I think I prefer it.
