Our Tuvix, who art in the transporter buffer, hallowed be thy name; thy episode come; on earth as it is in the delta quadrant. Give us this day our daily orchid. And forgive us our trespasses, as we forgive those who trespass against us, especially that bitch Katherine Janeway. And lead us not into moral dillemas; but deliver us from evil.
