From the movie Terminator 3: Rise of the Machines
If you have not seen the movie, here's a short summary to give you come context:
John Connor in the middle of the night breaks into a pet pharmacy to steal a bunch of pills because he's suffering emotional breakdowns or something like that. But the person who works there by pure chance also arrives at work a few moments later. She catches him and is about to call the cops. John Connor has a paintball gun on him. He whips it out and points at her with it, but messes up for a second which gives the pharmacy worker a chance to wrest it from his hands and fire a few rounds, but Conner is unharmed because the gun is obviously not real. Despite all that, she manages to kick his butt into a big cage for animals and lock him up in there. And then she says this:
Next time bring a clue, not a paintball gun.
I have no idea what she's saying.
I might not be one hundred percent accurate in my description, but that's the basic idea of what was going on in the scene.
