The Reasonabilists (also known derogatorily as "Zorpies") are members of a cult who follow Zorp the Surveyor, whom they believe will destroy the world. For some time in the 1970s, they took over the city of Pawnee, Indiana, but, as of 2011 were reduced to a small and harmless band of acolytes led by Herb Scaifer. They feature in the Season 4 episode "End of the World".
