Sherlock Holmes: You've never complained about my methods before.
Dr. John Watson: I'm not complaining.
Sherlock Holmes: You're not? What do you call this?
Dr. John Watson: I never complain! How am I complaining? When 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: Uh, we have a barter system...
Dr. John Watson: When have I ever complained about you setting fire to my rooms?
Sherlock Holmes: Our rooms...
Dr. John Watson: The rooms! Or, or, the fact that you experiment on my dog?
Sherlock Holmes: Our dog...
Dr. John Watson: The dog!
Sherlock Holmes: Gladstone is our dog!
