Sally: Okay, okay, okay, let's focus here. How do you kill somebody who can predict the future? We'll have to do it...
Harry: Unpredictably.
Sally: Right. Like an accident.
Harry: But how do you plan an accident?
Sally: No, no, no. You can't. But you can accidentally plan to accidentally kill somebody.
Harry: By accident.
Sally: Yeah, yeah, yeah. Like she could be allergic to shellfish and you accidentally run her over with your car.
Harry: That's a good plan.
Sally: Eh. Oh, no! It's not gonna work, though. I mean, if we already planned it, it's no longer an accidental plan.
Harry: Well, that's too bad, 'cause it was a good one.
