The Memoirs of Sherlock Holmes1994

Sherlock Holmes:
If I'm to have a doctor, at least let me have someone in whom I have confidence.

Doctor Watson:
[Gravely] You have none in me.

Sherlock Holmes:
Your friendship, yes. But I mean you're only a general practitioner with mediocre qualifications.

Doctor Watson:
That remark is unworthy of you, Holmes. It shows me very clearly the state of your nerves.

Sherlock Holmes:
That demonstrates your ignorance!

[shouts]

Sherlock Holmes:
What do you know about Tapanuli fever! What do you know of the black Formosa corruption!
