Flash mob pillow fight pummels Copley Square

Looking to unleash some pent up frustration by knocking a random stranger upside the head? You’re in luck.

While the first rule of fight club is you don’t talk about fight club, the upcoming International Pillow Fight Day at Copley Square is an entirely different story.

Promoters are trying to knock out the competition in NYC, Washington D.C. and London by organizing the largest flash mob of pillow-wielding participants in nearly two dozen cities. Some locations are expecting more than 700 folks.

The rules are simple. Show up at Boston’s Copley Square 1:55 p.m. on Saturday, March 22 with a soft pillow in hand. Don’t hit anyone who isn’t armed and slip off your shades if you’re wearing them. Go at it when the air horn sounds off at 2 p.m.

Organizers ask participants to remain on the down low, if possible. However, with hundreds of crazies walking around Copley Square holding pillows, discretion is highly unlikely.
