Sherlock: For a brief stretch in London, I talked only to a phrenology bust I kept in my study. I named him Angus. It wasn't the same. I realized when it came to listeners preferred animate to inanimate. It was quite a break through.
Watson: Angus. I am glad I made it to the animate category.

Sherlock: What are you doing?
Watson: Depriving you of all stimuli; time for you to get some sleep.
Sherlock: What? No, no. Right after you solve a case, you're flushed with a success. We should double down with work.
Watson: We?
Sherlock: You, me, Angus, some combination of the three. You already know I favor you.

Aaron: What is I.M.L.T.H.O?
Sherlock: In my less than humble opinion.
Watson: You're abbreviations are becoming borderline indecipherable. I don't know why, because you are obviously capable being articulate.
Sherlock: Language is evolving Watson becoming a more effective version of itself. I love text shorthand. It's a way you to convey content and tone without losing velocity.

Jim: My name is Jim Fowkes. I am the chief vestment officer. This is Daniel Cho our Chief Financial Officer another in-house board member.
Sherlock: Yep. You're all chiefs of something. What do you want?

Sherlock: Bit of a letdown actually, I think I could have gotten 20 times my normal rate.
Watson: What is your normal rate?
Sherlock: Oh. I don't have one, remind me to make one up before we leave.

Gregson: Do we have something to talk about?
Sherlock: There are any number of reasons why I didn't tell you about my history. I told myself dozens. In the end it's simple, I was embarrassed.
Sherlock: I am sorry, you deserved to know.
Gregson: I DID know.
Sherlock: I beg your pardon?
Gregson: Do you honestly think I would let you consult for the NYPD without doing my homework?

Sherlock: Learning to see the puzzle in everything? They're everywhere once you start looking, it's impossible to stop. It just so happens, people and all their deceits and illusions that inform everything that they do tends to be the most fascinating puzzles of all. Of course, they don't always appreciate being seen as such.
Watson: Seems like a lonely way to live.
Sherlock: As I said, it has its costs.

Idiots rely on luck.

Joan: You said the attendant was a friend of yours?
Sherlock: We post in the same bee keeping chat room. He has an impressive amount of Caucasians.... Species of bee.
Joan: Of course it is.

Sherlock: Interesting she didn't refer to you as her friend, probably because of your falling out. You call her by a familiar nick-name but yet you haven't spoken in a year and a half. What was that threw you two apart? Man? Job?
Joan: He's got a form of turrets.

Joan: "Better lucky than good". Sounds to me like you were lucky.
Carrie: Yeah, I guess I was.
Joan: I know what it's like not to be lucky, it turned my life upside down.
Carrie: You were always a good friend Joanie, but you were a better doctor.

Watson: How do you do it, guess things?
Sherlock: I observe and then I deduce.
Watson: How did you know I was a doctor, you said you could tell from my hands.
Sherlock: Hand, singular. It was soft no calluses.
Watson: How did you know my father had an affair?
Sherlock: Google. Not everything is deducible.
