The feathers are flying in cities around the world for International Pillow Fight Day today. 

Trafalgar Square in London was shut down for hundreds to bop one another and thousands more have taken to the streets of Berlin, Hong Kong, Rome, and Abu Dhabi. 

Events are planned across the U.S. in most major cities.

Information about local events for those looking to take a swing or two can be found at PillowFightDay.com.
