I don't know how we missed this, this would be like a National holiday for the DUmp! :D
Today (April 4th) is International Pillow Fight Day; and from Amsterdam to Kuala Lampur, more than 70 cities around the world (including NYC and Moscow) have scheduled a place and time for an old-fashioned pillow fight.
It sounds like a lot of fun and for sure it is a way of getting rid of some anger issues without doing any harm!
Check some pictures and videos from previous city pillow fights and see if there is one scheduled in your city.
