Sherlock Holmes: You've never complained about my methods before.
Dr. John Watson: I'm not complaining. How am I complaining? When have do I ever complain about you practicing the violin at three in the morning, or your mess, your general lack of hygiene, or the fact that you steal my clothes?

Sherlock Holmes: You have the grand gift of silence, Watson. It makes you quite invaluable as a companion.

Sherlock Holmes: [to Watson] Never theorize before you have data. Invariably, you end up twisting facts to suit theories, instead of theories to suit facts.

Irene Adler: I've never woke up in handcuffs before.
Sherlock Holmes: I have. Naked.

Sherlock Holmes: My mind rebells at stagnation. Give me work. Give me problems.
