Book excerpt: "The Comic Offense from Vaudeville to Contemporary Comedy examines how contemporary writer/performers are influenced by the comedic vaudevillians of the early 20th century. By tracing the history and legacy of the vaudeville era and performance acts, like the Marx Brothers and The Three Keatons, and moving through the silent and early sound films of the early 1930s, the author looks at how comic writer/performers continue to sell a brand of themselves as a form of social commentary in order to confront and dispel stereotypes of race, class, and gender. The first study to explore contemporary popular comic culture and its influence on American society from this unique perspective, Rick DesRochers analyzes stand-up and improvisational comedy writing/performing in the work of Larry David, Tina Fey, Stephen Colbert, and Dave Chappelle. He grounds these choices by examining their evolution as they developed signature characters and sketches for their respective shows Curb Your Enthusiasm, 30 Rock, The Colbert Report, and Chappelle's Show"--.
