Let's Make It a Group Effort

So ... I'm walking across the West Side Highway, coming upon a construction site where a new highrise condo is sprouting. I glance to my right, and there's a group of five or so men standing about, each facing a wall. It took a second or two for me to figure things out, but I eventually realized that they were all peeing! What the hell? It's not as if I've never witnessed public urination. But my sense is that it's typically a one-man sport. The sight of synchronized public urination is definitely a first for me. And it was in broad daylight, no less! Ah, the joy of living in NYC.
