Mo Rocca interviews Chris Rock: of note is his discussion of preachers and the influence on his stand-up. Preaching as a riffing style is part of it, but the ethnopoetics are also a factor, especially among black comedians. Bruce A. Rosenberg's The Art of the American Folk Preacher was a big influence on my understanding of stand-up, and one day I need to develop the oral-formulaic theory as it relates to the routines. Meanwhile, ethnopoetic transcription is the only way to make the stand-up's words live on the page.
Special thanks to bestie Andrea Kitta (@andreakitta), who not only wrote the definitive book on the anti-vaccination movement but also watches CBS Sunday Morning as if her life depended on it.
