At the risk of being NSFW, I offer the following puerile observation.
On my recent tour of the "upper High Line" area, I passed a gallery exhibit entitled NAKED! A better title would be PENIS! because all of the images were of naked men, or just disembodied penises.
Anyway, when I stepped outside the door, I noted a curiously shaped puddle on the sidewalk.
Did the curator plan this?
