The essential ingredient of 'the end of the world' is a voluble guy with the obligatory beard, dragging the band of true believers up a mountain on the evening of the last day. (they always go up some mountain - wouldn't be the same without one)
What they expect to find up there is a mystery and they always ascend in good summer weather, perhaps god the stonemason will carve them some special 'ahem..' commandments.
The euphoria is somewhat dissipated by morning and hunger helps lucidity reassert itself. The now rather sheepish group run the gauntlet of ridicule as they quitely merge back into sanity and forever question the decision.
The group now finds itself added to Mondo's list of 'Last Day Adventurers' as they resume normality.
