It's hardly the first time I've inspired a writer, Watson. I am actually the basis for several fictional characters across various media.

Sherlock

No, thanks, I had poop for lunch.

Joan

You are one of the best liars I have ever met, and that's saying something.

Sherlock

Henry Watson: How'd you know that was me?
Joan: 'Grover Ogden'? We lived on Ogden Avenue, Grover was our dog, and by the way, that's how you make a PORN name, not a PEN name!

[regarding her father's book] It's ridiculous! Sherlock and I do not run around with guns, and we don't get into kung fu fights with criminals, and we sure as hell do not sleep together!

Joan

Sherlock: Are you suffering from Low T?
Morland Holmes: ...Excuse me?
Sherlock: A deficiency, an imbalance in your hormone levels. Is it what's causing this late-onset humanity that you've been exhibiting since your return to New York?

Morland Holmes: I know we rarely spoke during your Scotland Yard days, but I do recall that you often made use of experts in other fields, your 'Unusuals.'
Sherlock: 'Irregulars.' And unless you've become an expert in sniping, I fail to see how you can assist here.

Unless you're dead, you're starting to annoy me.

Joan [to Sherlock's voicemail]

Morland Holmes: The value of your dam is $2.3 billion in theory only. It can be zero if I call certain friends in Lima.
Bill Wellstone: Now that, boys and girls, is how you deliver a threat. It's far more compelling than a warrant.

Morland Holmes: [about Lukas Muller's predecessor] We had a long and prosperous relationship, until one day he decided it wasn't quite prosperous enough.
Interpol Agent Lukas Muller: My God, Morland. His *children* found him!
Morland Holmes: They were *meant* to. Tell me, Lukas. How are your daughters?

You know what doesn't scare me at all? Comin' back to my garage and finding that some strange white guy let himself in. Not like that's ever gone badly for me!

Alfredo

Sherlock: Your 'help' has just resulted in that man's murder. Again.
Joan: Okay, first of all, he wasn't murdered, he was zapped into another dimension. And second of all, he still has two lives left.

Elementary Quotes

Holmes: Why do you suppose you hate your job so much?
Watson: I don't hate my job.
Holmes: You have two alarm clocks. No one with two alarm clocks loves their job. Two alarm clocks mean it's a chore for you to get up in the morning.

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.
