" Now, there was a certain guy etiquette when it came to urinals. If possible, always piss two urinal lengths apart. It was just courtesy, man. I didn't make the rules, but they've been there since the dawn of time. Hell, cavemen probably had a system like, stand two woolly mammoth femurs away or something. They'd say it in grunts and shit. Like two grunts and a bark meant, "Two femurs, bruh. Two. "
