Tina Fey
Fey played an extra in one of the episodes in 1998. After watching herself, she decided to diet. By dieting she lost 30 pounds. She told The New York Times, "I was a completely normal weight. But I was here in New York City, I had money and I couldn't buy any clothes. After I lost weight, there was interest in putting me on camera." In 1999, McKay quit as head writer. Michaels asked Fey to replace McKay. She became SNL's first female head writer. Fey does not make a big deal about this accomplishment because there have not been very many head writers.
