Brain: Why should a shrew be any different?
Brain: I don't know. Maybe I identify more with a shrew.
Brain: Did you hear that?
Brain: What do you mean you identify more with a shrew?
Brain: A shrew is more like my body than a fly. A shrew has a heart that pumps red blood through veins and arteries, a liver, lungs and a stomach. It even has a brain.
Brain: Interesting. Would it be safe to say that the more you identify with your victim, the more excited you get?
Brain: I don't know. Probably. I don't think of it in those terms. "Excited" is the wrong word.
Brain: Interesting. Then killing another man would be most exciting of all?
Brain: Yes. I told you "exciting" is the wrong word.
