Brenda Firth

A melicious tyrant who reins supreme over the commonwelth of Concord, New Hampshire, the thunderous sound of her rath can be heard from miles around. She has broken many legs, as well spines. She is not to be trifled with. If you see a Brenda Firth lerking in the Amazonian rain forest of Concord curl up in a ball and kill yourself, before you yourself brutally murdered.

Yeah my father was brutally mudered by the legendary Brenda Firth. I saw Brenda Firth feasting on her kill, the other day.
