The local Act-Up group went around spray-painting pink triangles on the buildings, sidewalks, walls, etc, all over campus. Some sort of a protest thing, I dunno. At any rate, the Campus paper and radio station kept holding this graffitti up as a fantastic thing, good to protest and bring enlightment, the perpetrators were open-minded and strong gay people showing their empowerment, etc etc etc.
One night, two people that will remain nameless decided that they had enough - please note that we, er, they had both consumed a liberal quantity of beer at the time. They went around with their own spray paint and put a circle and slash through all the pink triangles they could find.
Next day, the campus paper headlined on the "criminals" that "defaced the campus" with graffitti and screamed that we needed to be brought to justice.
Fortunately, the perpetrators still remain at large, years later. Hope that the statue of limitations has run out.
