Long ago we needed some burlap for a background for a photo shoot. The fabric store had a bolt of it and I bought several yards of burlap. As the lady laid it out to cut it I felt of it and said "yep that will make some great underwear." She paused for a second and then said she was pretty sure I was kidding. I said yep that stuff would suck for underwear. She said two guys had been in the day before and they bought several yards of vinyl cloth that looked like rubber and they said the same thing. She was pretty sure they were not kidding however.
