 "Private Parts" drew favorable comparisons to Lenny Bruce and his book "How to Talk Dirty and Influence People", but it was also characterized as nothing more than an extension of his radio show with little more to offer.Stern was praised for his populist message and attracting a group of people who normally do not read either by choice or for lack of ability.Another frequent criticism was that the material was juvenile, with little more to offer than stories of "breasts, behinds, penises, masturbation, defecation, and the expulsion of gas".
