I was on the bus on my way home from work this morning when I turned to my right and looked at the dress a woman beside me was wearing. Hmm� that looks like a pattern of red blood cells in slightly acidic urine. Then the dress of the person sitting behind her caught my attention. Now that looks like a pattern of urine triple phosphate crystals. I then looked at the clothing of the woman sitting behind the second person... and was relieved to see that she was wearing jeans and a t-shirt with words on it--no urine elements there. I've wondered about it from the beginning, but I guess it's true: looking at piss too much really can change the way you think.
