I didn't have a bag of characters that I could start pulling from. I didn't have a writer that wrote for me," she said. "I wasn't a stand-up. I was just this actress hoping to get material that I could then make funnier."
Larry David (1984-1985)

Gilbert Gottfried (1980-81)
Gottfried struggled to get airtime during his 12 episodes with SNL, and was even reduced to playing a lifeless corpse in one sketch. "I was there right after the original cast left, and so back then it was like 'How dare they continue Saturday Night Live without the original cast of people?' " Gottfied said in 2012. "Back then it would be like if in the middle of Beatlemania you just said 'Oh, the Beatles are not John, Paul, George, and Ringo -- it's Harry, Artie, Phil,' you know? It was an outrage. So before we even got on the air, they were already writing these articles: 'Who the hell are these people?' "
