Word origins are always good. The origin of the word trivia is on this site somewhere, but my favourite is the origin of the word sabotage. Before sholaces there were two basic types of shoes, clogs, and those ones with the buckles which are sabots. When someone invented shoelaces sales of sabots went downhill rapidly In protest the sabot makers made sure the people making sholaces didn't have an easy time and would do anything to ruin the production line. Hence sabotage.
