See this really filthy toilet bowl? I've lived it in for the last 20 years, and I've always thought it was disgusting. I never said anything, but I always thought it was gross. Now, I'm going to scrub this dirty toilet bowl with a hunk of human feces.
Sure, human feces caused the stains, and they are the reason that the bowl is disgusting, but I'm convinced that if I scrub really really hard, feces will clean up feces.
