Amy Poehler: Then and now

SNL: Dakota Fanning Talk Show

Celebrity impersonation is key to any successful stint on "SNL." Some have done it well (sigh, Phil Hartman) and others have done it astonishingly poorly (ugh, Jim Breuer). Amy’s Hillary Clinton, Nancy Grace and Sharon Osbourne all rocked the proverbial Kasbah, but “The Dakota Fanning Show” put them all to shame. Is there anything funnier than hyper-literate child stars?
