Cobb : What do you want from us? Saito : Inception. Is it possible? Arthur : Of course not. Saito : If you can steal an idea from someone's mind, why can't you plant one there instead? Arthur : Okay, here's me planting an idea in your head: I say to you, "Don't think about elephants." What are you thinking about? Saito : Elephants. Arthur : Right. But it's not your idea because you know I gave it to you. The subject's mind can always trace the genesis of the idea. True inspiration is impossible to fake. Cobb : That's not true. Saito : [to Cobb] Can you do it? Cobb : Are you offering me a choice? Because I can find my own way to square things with Cobol. Saito : Then you do have a choice. Cobb : Then I choose to leave, sir.
