Jules does a great job of using the sparkly in the case (did we ever figure out WHAT was in the case?) to draw Ringo's attention.
I was loaned out to an agency circa' '96-'98, buying crack and we had a hard time capturing guys on the video cameras we had installed in the car. They were wise to it and did a good job of keeping their faces above the roofline of the car to avoid getting captured.
My solution was to get the centerfold of a hot naked girl in an explicit porno mag and open it up where it was laying on the passenger seat propped open with other crack-head detritus and back drop like half empty bottles of malt liquor and crumpled Newport cigarette packs. When you add in a Watec 660 board camera shooting out of a pinhole in the passenger side arm rest across the driver's side, it made it easy to grin kinda' silly and say to a dude "Hey man..check out mah' girl" and watch him say "DAAAYUM!" and get him to chicken neck inside the driver's side window and get a full face shot for ID.
Same principle, different application.
