I've always been fascinated with the crude unintentional artwork of telephone pole "lost" signs. Usually a black-and-white photo and some handwritten notes, they always seem so earnest and yet are so easily ignored.
So it was that I set out to exploit these properties for a Web site I was working on with a friend, lowfashion.com. I made up fake flyers, had a hundred or so printed out, and even thought for quite a bit about posting them up around my neighborhood.
In the end, a combination of laziness and fear of appearing insensitive to the lost-pet lobby prevented me from actually posting the flyers anywhere besides the lowfashion.com Web site (and now here, gentle reader). I still think it would be humorous to find such a seemingly random poster on a telephone pole as I walked down the street, though.
