This is one of my favorite Lenny Bruce bits of all time - a doped-up 50s hipster getting a job on Lawrence Welk's definition-of-square variety show. For some reason, they edit out Lawrence Welk's name. This isn't the best version; I prefer the one which ends with Welk commenting on the hipster's eyes being so smaaall instead of he monkey part.

Below is one of my favorite of his routines; conveniently, it's one of the ones that has held up the best, language-wise. For most of his other work, it take some effort to get past 1950s hipster slang, the media references (speaking of which: this is George Macready,) and his unstoppable delivery, but it is all worth it.

There's a part I love, from the middle of a routine, in a conversation between him and some midwestern Jews: “You from New York?” “Yes.” “Are you Jewish?” “Yes.” “What are you doing in a place like this?” “I'm passing.”

Moreover, as he goes into the absurdity of his multiple obscenity convictions, it becomes an time capsule and oral history of 1960s stage culture. That being said, here's a somewhat lighter bit:
