Quote from Dorothy in Wham, Bam, Thank You, Mammy!
Blanche: That call. It was Viola Watkins. She used to be my mammy. Dorothy: Your what? Blanche: My mammy. The woman who took care of me when I was little. Dorothy: Oh, I'm sorry. I don't think I ever heard anyone called "Mammy" before. Rose: What about Mrs. Eisenhower? Dorothy: "Mammy" Eisenhower? I think only the Nixon kids got to call her that.
