Why I had to pee so badly last Thursday

I went to the University of Western Australia last Thursday for a morning meeting. I parked the car and dashed into the Physics building, arriving on time with only seconds to spare. The meeting finished an hour or so later and I left, ending up back in a quad on campus.

I was disoriented. Where was the car? Left? Right? North? South? No worries, I thought. I'll just walk until I find it. On my way to re-discovering the car's location, I came across an interesting sculpture on the UWA campus. It is called the Orbicular Granitoid Fountain. Really, it's quite obvious once you think about it.

And after observing it for several seconds, I had to pee really badly.
