Dr who sixth doctor quotes Attack of the Cybermen

The Doctor: Rest is for the weary, sleep is for the dead.

The Doctor: A little gratitude wouldn't irretrievably damage my ego.

Peri: Look Doctor, ever since you regenerated, i-it's as if your memory has been put through the meat grinder. I mean, it's all there, but in a pile of unrelated bits and pieces.

The Doctor: That's a horrible simile.

Peri: It's true, though. In the past couple of days, you've called me Tegan, Zoe, Susan. On one occasion, you even referred to me as Jamie.

Peri: But Doctor, you said it was gunfire!

The Doctor: I heard me.

Peri: I only hope it believes you.

The Doctor: Well if it doesn't, I shall beat it into submission... with my charm.

The Doctor: Sorry about that, but we weren't getting anywhere with me playing pat-a-cake with the wall.

Russell: You're bonkers.

The Doctor: That's debatable.
