Grey's Anatomy, Season 8

[to Meredith] You want to waste your talent playing with one little predictable organ for the rest of your life? Nah, I'd rather spend my days leaping from the liver to the pancreas to the stomach to the bowel, and any one could go wrong at anytime. There's nothing wrong with knowing one organ and knowing it well, just like there's nothing wrong with being fifth-chair viola in the back of the orchestra. But it's a hell of a lot more fun being the conductor.
