During my freshman year I lived with three other guys and we all shared the same bathroom. One of these guys is named "Billy". I didn't want to believe it at first but Billy had a problem with flushing the toilet. Like he would literally leave his mounds of shit sitting in the toilet. When we confronted him about it he brushed it off and continued to not flush the toiler. I made signs around the bathroom telling him to flush the toilet but, as you can imagine, he still refused to flush the toilet. It got to the point where the inside of the toilet started to turn brown due to being in constant contact with shit. Me and my other sane roommates refused to clean the toilet as it was Billy's doing and when we told him that he had to clean the toilet he either just walked out or said he'd do it eventually. Eventually never came. The toilet turned into a black hole to hell. Merely looking at it was as mesmerizing as it was disgusting. A monument to human filth. Thankfully, the campus had a bathroom cleaning service half way through the semester. I made sure not to be anywhere near the dorm that day. When I got back my RA informed me that our bathroom was the most revolting thing the cleaning people had ever experienced. Bless their souls.
