Although this is probably of little interest or amusement value to those who do not remember the joys of living through the dying years of John Major's increasingly incompetent government, it does raise the point that the word "green" has gained a new meaning since Chomsky coined the phrase, and that thus semantic drift has the power to make (some kind of) sense out of nonsense.
