Sorry for saying that, but there is good news. There is a charity organization that gives dying children one last smile. It is called Famous Fone Friends (Pardon the misspelling, they wanted to be clever.) Who gets people who have terminal ilnesses, young and old, a chance to talk to their favorite actor or even some Toons.
Celebs who are in this include Bill Farmer (Voice of Goofy), June Foray (Voice of Rocky from Rocky and Bullwinkle, and known to Roger fans as Wheezy the Weasel and Leena Hyeena) and Roger Rabbit.
Jess Harnell is an impressionist and voice actor. Some of his notable roles include Br'er Rabbit in Splash Mountain, Wakko Warner on Animaniacs, and fills in for Charles Fleischer for Roger if Charlie cannot do recordings. For this, Jess talks to children who are terminally ill as Roger for charity.
