Amy Poehler is leaving Saturday Night Live to give birth to her first child. There's only one problem, she's not coming back. "It's gonna be really hard -- Boyz II Men hard -- to say goodbye to yesterday," Poehler said in an interview. " 'SNL' was dangerous, late-night, last-minute and star-studded, but like any good drug, you need to know when to put it down." Instead of returning to the SNL cast, and gracing us with her hilarious portrayal of Hillary Clinton, Poehler will be staring in her own NBC series from the executive producers of The Office.
