"Where does virgin wool come from? The sheep that runs the fastest"

This quote by Harry F. Banks is a funny method of suggesting that the source of virgin wool is the sheep that runs the fastest. It implies that the wool from the fastest sheep is the most preferable and of the highest quality. This quote is likely suggested to be a lighthearted joke, as it is difficult for a sheep to run quick enough to produce virgin wool. It is most likely that the wool is drawn from a sheep that has actually not been shorn previously, thus making it "virgin" wool. The quote is a funny method of suggesting that the best wool comes from the fastest sheep, which is an impossibility. It is a smart method of highlighting the significance of quality wool and the effort that enters into producing it.
