From the onset of her first appearances on "Saturday Night Live" (NBC, 1975- ), Cheri Oteri fully explored her gifts for provoking laugher. Her spot-on mimicry of celebrities such as Barbara Walters and Judge Judy Sheindlin, along with a wide range of bawdy and perky originals - including cheerleader Arianna, feisty Rita Del Vecchio and talk show host Cass Van Rye - helped the petite comedy dynamo anchor the show's late 1990s resurgence, stirring viewer adulation and kick-starting her big screen career.
