Cyberman: Daleks, be warned. You have declared war upon the Cybermen.

Dalek: This is not war. This is pest control.

Cyberman: We have five million Cybermen. How many are you?

Dalek: Four.

Cyberman: You would destroy the Cybermen with four Daleks?

Dalek: We would destroy the Cybermen with one Dalek. You are superior in only one respect.

Cyberman: What is that?

Dalek: You are better at dying.
