Doctor Who Quote of the Day

From Blink, an episode in season three of Doctor Who:

The Doctor: People don't understand time. It's not what you think it is.
Sally: Then what is it?
The Doctor: Complicated.
Sally: Tell me.
The Doctor: Very complicated.
Sally: I'm clever, and I'm listening, and don't patronise me because people have died and I'm not happy. Tell me.
The Doctor: People assume that time is a strict progression of cause to effect... but actually, from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly.... timey-wimey.... stuff.
