understanding Walt's vision

Tonight in the car, Dennis said "I just wish the whole world would be just like Disney World!". We asked him to elaborate. He told us "I would be Mickey, and Mommy, you would be Minnie, and Daddy would be Goofy, and Pop would be Pete, and Bob would be Pluto, and Uncle George would be Donald Duck, and my great great grandfather in Heaven would be another Donald Duck." We asked who Gran would be, and he said "she would just be a regular girl, and Uncle Denny would be another Goofy." He laughed at his world vision but got mad at us for laughing along with him.
