Dr. Watson: I do have a couple of other things on my mind this evening.
Sherlock: Like what?

Dr. Watson: You are kidding? What's so important? Sherlock, I'm right in the middle of a date. You're going to chase some killer while I'm trying to...

Sherlock: What?

Sherlock , either way

Sherlock, Series 01, Episode 01, A Study in Pink


Jeff: It's pure genius. I know how people think. I know how people think I think. I can see it all like a map inside my head. Everyone's so stupid, even you. Or maybe God just loves me. 
Sherlock Holmes: Either way, you're wasted as a cabbie. 


either way: used to say that something will be the same whichever of two things happens or is true.

Dr. John Watson: That's good news for breathing. 
Sherlock Holmes: Ah, breathing. Breathing's boring. 
Dr. John Watson: Is that three patches? 
Sherlock Holmes: It's a three-patch problem. 


Like a five-pound note (a fiver) or a ten-pound note (a tenner)

Sherlock Holmes: But? 
Dr John Watson: But the police don't consult private detectives. 
Sherlock Holmes: I'm a consulting detective. The only one in the world - I invented the job. 
Dr John Watson: What does that mean? 
Sherlock Holmes: It means when the police are out of their depth - which is always - they consult me.
