HBO films Phyllis Diller in a live stand-up performance - taped in Denver, Colorado - in Phyllis Diller: On Location. Known for her biting wit and caustic laugh, Diller - though semi-retired - recently appeared and gained renewed popularity in the acclaimed The Aristocrats. She delivers an extended routine in this home release, using as the basis of much of her material a subject that has become her trademark over the years: the foibles of her ex-husband 'Fang.'
