Sarah Silverman
Sarah Kate Silverman (born December 1, 1970) is an American comedian, writer and actress. Although usually credited as Sarah Silverman, she is sometimes credited by her nickname Big S or Sarah 'Big S' Silverman. Her comedy deals with topical humor and satire, societal taboos, and controversial topics such as racism, sexism and religion.
Her comedy acts are sometimes performed from a caricatured or stereotypical Jewish-American princess perspective, in which, according to Village Voice writer Michael Musto, she mocks bigotry and ethnic or religious stereotypes by endorsing them ironically. Silverman was first noticed as a writer Saturday Night Live. She now stars in and produces the The Sarah Silverman Program, which debuted February 1, 2007, on Comedy Central.
