Anyway, Phyllis Diller was part of what Time Magazine in 1960 called “The New Wave Comedians”, guys like Bruce, Newhart, Sellers, and Allen who began their careers after WWII and had no connection to vaudeville. Essentially, they invented modern standup comedy and made the college crowd their audience. It reflected the development of a more sophisticated and better-educated America during the 50s that had evolved beyond laughing at the Three Stooges hitting each other in the heads with mallets (note that the Stooges’ postwar stuff was primarily aimed at children rather than adults).
