 This episode features a guest voice by Thomas Pynchon (qv), the  legendarily reclusive author of such novels as "V" and "Gravitys  Rainbow." Prior to that, Pynchon had never granted an interview, or  even allowed himself to be photographed, so the appearance was quite  literally the first time his voice had been heard publicly. He also  did a voice for the 16th season episode "Alls Fair in Oven War".
