8. Amy Poehler
She got more amazing every year. She could do warmth, yet was always buzzing with a real don't-mess-with-me hostility never far from the surface. The ultimate pro — the way she read and responded to the people around her raised everybody's game. She revived the ancient concept that the "Weekend Update" anchor should also raise hell the rest of the show. Poehler and Fey have more chemistry than any SNL duo since the Blues Brothers. It's a tragedy if they don't host every awards show from now on.
Greatest hit: Betty Caruso on "Bronx Beat," an urban mom grousing about her husband, the weather and everything else. ("You know what word I hate? 'Hemoglobin!' ") You can see that caustic edge in the way she sneers when Maya Rudolph starts to cry: "Here we go with the waterworks!"
