Strangest thing found in your A body???

when we were restoring my Dart last year, I was finally getting around to getting the trunk lid done.. In between the structure and the outer skin we found an old street hockey puck wedged in there.. never knew it was in there... we couldnt find a brand name on it, but it appeared to be quite old.. probably been riding around in that car since the 70's lol... How it got to where it wound up is a bit of a mystery.. all we can figure is it bounced around in the trunk, found its way in and came to rest there.. I bet when whoever owned the car back then got to the street hockey game, they were probably confused about what became of the puck LOL
