A friend was visiting the London and made the aquaintance of a seemingly normal fellow who had a strange hobby : he would disable a public toilet (so that it could not be flushed) and then wait until someone used it (presumably to take a sh!t, as pee-ers would use a urinal), then go back in and take a picture of the unflushable results of their visit. The resulting photos then went into an album. If this wasn't
enough, the pictures were all captioned w/ a physical description of the sh!tter/ location/ date. E.g. "Large Indian man, St. Pancras Station, 26/0312", or "West Ham Supporter, Drayton Arms, 15/10/09"
