Kevin recently found this plastic thingie on his bus.  We didn’t know what it was, but I knew how to find out.  So I took a picture of it with a solid background and used Google Image Search to find out what it is.  Google showed similar images found on the web, and we quickly learned that it’s a earbud cord hanger.  You wind your earbud wires around it to keep them from getting all tangled up in your pocket.  Kevin is using it now, and it works.
