One of my favorite Dr Who 9 quotes

[collwen]

The Doctor: Do you know like we were saying, about the earth revolving? It's like when you're a kid, the first time they tell you that the world's turning, and you just can't quite believe it cuz everything looks like it's standing still. I can feel it. The turn of the earth. The ground beneath our feet is spinning at a thousand miles an hour, and the entire planet is hurtling around the sun at 67000 miles an hour. And I can feel it. We're falling through space, you and me, clinging to the skin of this tiny little world, and if we let go... That's who I am. Now, forget me, Rose Tyler. Go home.
