Sherlock, Series 3

Mycroft Holmes:
I have given the Prime Minister my personal assurance that you're on the case.

Sherlock Holmes:
I am on the case. We're both on the case right now.

[A buzzer sounds. Mycroft and Sherlock are revealed to be playing Operation - not chess]

Mycroft Holmes:
Oh, bugger!

Sherlock Holmes:
Whoopsy! Can't handle a broken heart. How very telling.

Mycroft Holmes:
Don't be smart.

Sherlock Holmes:
That takes me back. [Mimicking Mycroft] "Don't be smart, Sherlock, I'm the smart one".

Mycroft Holmes:
I am the smart one.

Sherlock Holmes:
I used to think I was an idiot.

Mycroft Holmes:
Both of us thought you were an idiot, Sherlock. We had nothing else to go on, until we met other children.

Sherlock Holmes:
Oh, yes. That was a mistake.

Mycroft Holmes:
Ghastly. What were they thinking of?

Sherlock Holmes:
Probably something about trying to make friends.

Mycroft Holmes:
Oh, yes. Friends. Of course, you go in for that sort of thing now.

Sherlock Holmes:
And you don't? Ever?

Mycroft Holmes:
If you seem slow to me, Sherlock, can you imagine what real people are like? I'm living in a world of goldfish.

Sherlock Holmes:
Yes, but I've been away for two years.

Mycroft Holmes:
So?

Sherlock Holmes:
Oh, I don't know...I thought you perhaps might have found yourself a...goldfish.
