64-65. The Two Nancys: Terry Sweeney and Mary Gross
Eras: Terry Sweeney (1985-1986); Mary Gross (1981-1985)
SNL's twin Nancy Reagans. Sweeney, the first out cast member, had an abrasive edge that sometimes hit the mark, and Gross was more polished — she also shone as Alfalfa and (especially) Mary Tyler Moore. Both were years ahead of their time.
