And that rhymes with potty, a word that sums up the humor in this vanity project from star and executive producer Paris Hilton. She plays a sexy LA event planner who’s besieged by suitors but has forsworn dating until her freakishly ugly roommate (Christine Lakin) lands a man. The roomie—a walking health hazard with rampant acne, discolored teeth, and a fungal toenail—knows that an amiable slacker (Joel David Moore) is being attentive to her only to get close to Hilton, and turns the tables when a hunky dentist (Johann Urb) offers her a cosmetic makeover. Heidi Ferrer wrote the misogynist gross-out screenplay; the limp direction is by Tom Putnam. PG-13, 91 min.
