My college roommate and I visited his younger brother one time, who was in a fraternity at Rutgers. One of the fraternity brothers had already left for either Thanksgiving or Christmas break, whichever it was. His room in the fraternity house had it's own bathroom, and everybody else had been shitting in his toilet, without flushing it, since he left. Used paper was thrown in a big garbage can. The pile was already up out of the water, but they wanted to get the peak crowning through the seat before everyone else left. It smelled about like you'd expect. It was even worse when they came back from break.
