MEDIC=Mister Claptrap, I have a medical proposition for you.

CLAPTRAP=Does it involve sexy nurses? Or hot nurses? Or hot sexy nurses?

MEDIC=I would like to install a human brain inside your robot body, running in parallel to your mechanical brain.

CLAPTRAP=A human brain? No offense, Doc, but are you out of your freakin' mind? Human brains are d-u-m dumb.

GLADOS=It's true. I'm outhinking all of the humans at this table right now, all the while simultaneously running fifty-two experiments back at Aperture. Make that fifty-one. Subject 19 has just bisected himself with a laser. See? That's what human brains do - they walk into lasers.

MEDIC=Ah, but just think of what a robot brain and a human brain could do together. The ruthless efficiency of a computer, combined with the empathy and creativity of a human.

GLADOS=Empathy is overrated. And creativity is just another word for mathematically-appealing randomness.

CLAPTRAP=She's right, Doc. The only thing human brains are good for distracting zombies.
