Tina Fey, Julie Andrews and Tony Bennett will salute actress Carol Burnett when she is honoured with the Mark Twain Prize for American Humor next month (Oct13). The Carol Burnett Show star will be feted at the Kennedy Center's 16th annual ceremony. A statement from the actress reads, "I can't believe I'm getting a humor prize from the Kennedy Center. It's almost impossible to be funnier than the people in Washington." Amy Poehler, Rashida Jones, Maya Rudolph and Lucille Ball's daughter Lucie Arnaz, and Burnett's former castmates Tim Conway and Vicki Lawrence will also be on hand to celebrate the comedienne. Previous honourees include Richard Pryor, Ellen DeGeneres, Will Ferrell, Fey, Bill Cosby and George Carlin.
