"The universe is big. It's vast and complicated and ridiculous. And sometimes—very rarely—impossible things just happen and we call them miracles."

"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... time-y wimey... stuff."

"Hitler: Thank you, whoever you are. I think you just saved my life.The Doctor: Believe me... It was an accident."

"The universe is big, its vast and complicated, and ridiculous. And sometimes, very rarely, impossible things just happen and we call them miracles. And that's the theory. Nine hundred years, never seen one yet, but this would do me."

"The Doctor: I've seen bigger.Clara: Really?The Doctor: Are you joking? It's massive!"

"You have to take your own bold approach, and if you do you will be rewarded with success. Or calamitous failure. That can happen too."
