Years ago the hot repairmens’ shop in one of my company’s plants had many gross nude pictures on the walls. One day a nun touring the plant with a bunch of school kids accidently
wandered into the shop. The pictures were gone the next day.
I was in the downtown garage one day waiting for a ride to outskirts of town where we drivers were required to park and turn in our fares and reports before day's end.
There was a calendar there with a racy model and a lugnut attached to a wire attached to the bottom. There was also a handwritten sign by the lugnut warning you not to pull it. Of course, I did and got my young eyes burned with the model displaying spread legs in full frontal nudity!
