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

Daleks: This is not war, this is pest control!

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

Daleks: Four.

Cybermen: You would destroy the Cybermen with four Daleks?

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

Cybermen: What is that?

Daleks: You are better at dying!
