Cobb: What do you want?
Saito: Inception. Is it possible?
Arthur: Of course not.
Saito: If you can steal an idea, why can't you plant one there instead?
Arthur: Okay, this is me, planting an idea in your mind. I say: don't think about elephants. What are you thinking about?
Arthur: Right, but it's not your idea. The dreamer can always remember the genesis of the idea. True inspiration is impossible to fake.
Cobb: No, it's not.
