15. Maya Rudolph (2000-2007)
With a distinctive sexy look and a masterful ability to pull off just about any and every accent, Rudolph (who's African American and Jewish, herself) was able to portray ethnicities across the board (Asian, Black, Latina, European), and without being subject to the same scrutiny as John Belushi. Thanks to her, the show was finally able to (at least vicariously) get some of that much-needed diversity. She also sang wonderfully and knew how to wear the shit out of a pair of mom jeans.
