I WAS going to wear my kickass pirate outfit, but I'm considering wearing my whole temple clothing set... just to remind everyone that yes, despite their pleading through ad campaigns, they ARE this batsh*t crazy.
At the social hour of the Ex-mormon conference four years ago a guy told about going to a halloween party in Park City wearing garments that said on the front, "My parents went to the temple and all I got was this stupid underwear." I think he said he left early because he was really upsetting some of the people.
