Missy Elliott's super freaky jams always sound like something otherworldly -- so it's no surprise that one of her best songs sets its cameo-stuffed video in a dingy sewer populated by a bunch of dancing girls, lots of dry ice and a pasty leather-sporting  freak. The scene occasionally shifts to a park filled with zombies, spiderwebs and even more dancing girls. It doesn't make a whole lotta sense, but it's probably not supposed to. Best moment of this Halloween video: Missy's head gets all stretchy, just begging for some 3D action.
