'I Was Such a Dog': 'The Carol Burnett Show' (1974)
Though Rivers' style was bold, physical and often as garish as they outfits she'd later favor, she could also approach an almost confessional atmosphere with her audiences. As absurd as some of the jokes may be ("I was such a dog, to get me down the aisle they threw a bone."), during this set the crowd leans in, rapt. Rivers, for her part, sells it as though she were finally letting her guard down and giving them the unvarnished truth.
