A New York judge has issued an arrest warrant for American Pie star Natasha Lyonne, who failed to appear for a court hearing Monday on charges that she threatened to, um, do bad things to her neighbor's dog during fit of rage last December. Police claim the 25-year-old actress stormed into the apartment, ripped a mirror from the wall and screamed: "I'm going to sexually molest your dog!" In her defense, the pooch was kinda cute.
