CNN Original Series examines the historic influence of comedy in an eight-part documentary. Archival footage and contemporary interviews with comedy legends, scholars and current stars combine to explore what makes people laugh and how comedy has affected history's social and political landscape. Judd Apatow, Sarah Silverman, Margaret Cho, Jimmy Kimmel, Kathy Griffin, George Lopez, Keegan-Michael Key, Conan O'Brien, Patton Oswalt and Dick Cavett are among those interviewed. The series begins by profiling "blue" comics like George Carlin and Lenny Bruce. Subsequent episodes detail women in comedy, political humor, parody and satire, comedy ripped from the headlines, the dark side of comedy, comedy in race and culture, and comedy found in everyday life.
