Elementary Season 1 Episode 1

Watson: It's so incredible, the way that you can, solve people just by looking at them. I noticed you don't have any mirrors around here.
Holmes: And what's that supposed to mean?
Watson: It means I think you know a lost cause when you see one.

Holmes: Tell me, how do clients typically introduce you?
Watson: What do you mean?
Holmes: I-I mean I find it hard to believe they'd actually tell someone they've been assigned a glorified helper monkey.
Watson: Helper monkey? Well, you and I have what's known as companion/client confidentiality, which means that you can introduce me however you like. Friend, coworker, relative, and I'll play along. But to be honest, most clients just call me their companion.
Holmes: Hmm. (continues with an introduction to Captain Gregson as "my personal valet")

Holmes: Sometimes I hate it when I'm right.
