years ago a buddy of mine lived in the city,he had an old olds cutlass diesel wagon.he had a cheesy steroeo in it with an under dash equilizer.well he was going to work one day and looks down on the tunnel and there was a screw laying there,he didn't think much of it,then a couple days later he see's another one and then thinks.man this diesel is shaking my screws loose.next morning he goes out and his equilizer is gone.he actually thought it was pretty funny that they took a few days to get it.well about 6 months later he was hauling junk to the dump this was on a saturday afternoon and he goes out and puts his dead black and white tv in the car and goes back in the house for more stuff,when he comes out his tv was gone.probably the same ones that took his eq.
