Professor Green was the individual who, single-handedly, had invented the means by which one could make the world a giant golf course, later stolen by a zealous Duff Killigan; "golf course" - "green," green of which is synonymous with, and predicates, the golf course, so it is reasonable to draw the conclusion Professor Green's surname, Green, could have been motivated by these details. In addition, his first name (as mentioned by Dr. Director) was Sylvan, a word meaning "heavily wooded or abounding in trees."
