A euphemism for phallic symbols common at Wiess near NOD time. According to George Hall (Wiess College President '81, College Idiot '79,'80,'81,'82), Sparky was the name of an eight foot long paper mache dildo built (and well built) for NOD in ~1980. He gained his fame by appearing in the Houston Post sports page bobing up and down in the student section at a Rice football game.
