Did you know there  is a World Pillow Fight Day? I didn’t either till after going to San Diego’s first pillow fight and kept in contact with some of the organizers.

It doesn’t appear to be a constant date for this annual event. While last years 2008 pillow fight was March 22nd in 2009 they had it on April 4th.  I think they’re trying to give a nod to other large pillowfights that were born out of flashmobs. Check the full gallery after the jump!
