When I was a teenager I worked in a small grocery store, it was the only one in the area. I was stocking shelves when a man approached me and asked if we sold "prophylactics". I said "I don't know but if you tell me what they are I can tell you were to find them."

He was forced to tell me what they were, I don't know who was more embarrassed, him or I. We did not sell them.
