I picked up several packages of pipe cleaners yesterday at a Goodwill. They are so handy for little jobs, thought $2 for a 4 pack was a good price. Got home and noticed one package was a different color, and looked at it more closely. It was a Walter Raleigh brand - for cleaning pipes! Then it hit me - pipe cleaners are for cleaning (smoking) pipes. I never knew!
I don't know what I thought they were named for - they were just called "pipe cleaners". Now I know better!
