(WHAT IT SAYS) The first rule of Pillow Fight Club: Tell everyone you know about Pillow Fight Club. Tonight at Re-bar, the freaks come out and bring their pillows and jammies with 'em, to bash each other for the entertainment of all. Amid the flying feathers, there will be drinking, dancing, and free-for-all battles, with the evening's grand-prize winner determined by the audience. (Re-bar, 1114 Howell St, 233-9873. 10 pm, $5, 21+.)
