No one was sleeping, but STL Improv Anywhere's pillow fight was like a slumber party gone wild anyway. The group held its third annual International Pillow Fight Day in Tower Grove Park on April 5, 2014, complete with costumes and special challenges, in addition to having participants simply beat the crap out of each other with pillows.
