Stars like Will Ferrell, Matt Damon, Oprah Winfrey and Kermit the Frog all stopped by
Played: Rosemary Howard in "Rosemary's Baby"
Nearly everything in "Rosemary's Baby" gets sucked into the brilliantly comedic black hole that is Jack Donaghy and Tracy Jordan's visit to the NBC shrink, but never forget Fisher's terrific, Emmy nominated guest appearance playing legendary, but bonkers, comic writer Rosemary Howard. The role was a loopy nod to Fisher's status as one of the top punch-up comedy writers in Hollywood and somehow let her utter the line "Help me, Liz Lemon! You're my only hope!" just to pander to the "Star Wars" fans, including Prince Leia-obsessed Liz Lemon.
