NEW YORK, NY - Gluey Bush’s abortive appearance on the Late Show with David Letterman is one the show's staff won’t soon forget.  The GOP candidate sent makeup girl Lisa Sandberg and former Secretary of Defense Donald Rumsfeld to the hospital with severe scratches and bite marks after he became irritated during Letterman’s Top Ten List.  While Gluey was receiving a thorough delousing backstage, someone made the mistake of turning on the dressing room television before his sedative was administered and his venom sacks could be drained.  When Gluey heard the sounds of human laughter and applause while not under the medicated haze of a powerful barnyard pharmaceutical, he slipped into an all too familiar rage.
