DOCTOR: But! If you travel through time, you will find lots of books about ME! And how I am fantastic. And you will give up. So you should give up now instead. Because of TIME.
DALEKS: No. We will travel through time and destroy all the books we would have read about you. Then we will destroy all of us who have heard about the book. For the sake of morale. We will destroy all of ourselves so we may continue. There will be one harmless Dalek left who knows nothing. And travels through time.
DOCTOR: I don't know if this counts as winning or losing.
DALEKS: With a companion.
