Have you ever heard the saying, "Dirty car, clean windows?" Well, that old adage comes from a former WENN photographer named Gary Sun who told the LA Times that was the way to 'spot a pap car.'
You see, the sneakier paps shoot pics through their car windows, and they need to be clean, to hell with the rest of the car.
Here we see a photog sitting on Kim Kardashian, diligently cleaning his windows. He's not doing it for his health people!
He's also sporting a paper plate, despite the fact that he probably received his real plates in the mail two years ago.
Hey celebs, this is really a warning sign that a pap is following you!
