It's not the crowds that are strange; it's a nice day, and people are enjoying it. No, you realize, it's the sheer, overwhelming number of people. People wearing funny costumes. And rabbit ears. And every single one of them has a pillow. "What on earth," you wonder, "is going on here?"
The clock strikes three and you get your answer. In unison, hundreds of people thrust their pillows into the air en masse, give a mighty war cry, and proceed to pummel the ever-loving snot out of each other. It is, you realize, a pillow fight in the middle of Washington Square Park.
It is randomly delightful. And that's really all there is to it.
a crowd gathers
some people are more prepared for the looming battle than others!
the call comes, pillows are thrust into the sky...
...and the fight begins!
feathers, feathers, everywhere
what a wonderful day in the park
