Sherlock, Series 2

Sherlock Holmes:
Mycroft, I don't do anonymous clients. I'm used to mystery at one end of my cases; both ends is too much work. [to the equerry who brought him in] Good morning.

[He starts to leave, but Mycroft stops him by putting one foot on the trailing sheet behind him, nearly pulling it right off]

Mycroft Holmes:
This is a matter of national importance. Grow up.

Sherlock Holmes:
[through gritted teeth] Get off my sheet!

Mycroft Holmes:
Or what?

Sherlock Holmes:
Or I'll just walk away.

Mycroft Holmes:
I'll let you.

John Watson:
Boys, please. Not here.

Sherlock Holmes:
Who. Is. My. Client?!

Mycroft Holmes:
Take a look at where you're standing and make a deduction. You are to be engaged by the highest in the land. Now FOR GOD'S SAKE... [forcibly calms himself] put your clothes on!
