Rita Rudner (58) Courtesy of lifeafter50.com The longest running, most-successful one person comedy show in the history of Las Vegas is Rita Rudner. Having sold over 50 million tickets to her shows, she's doing something right. Creating believable, intrinsic, observational humor, Rita has entertained audiences in droves and shows no signs of slowing. Unlike a lot of comedians today, she hasn't come through SNL or Comedy Central. Crediting Woody Allen and Jack Benny as her inspirations, she has a biting wit and sarcasm spoken in a warm friendly tone.
