Of the beginnings of SNL, Shuster has said, "There was a long incubation period where everybody was kind of falling in love with each other and cracking each other up, trying to find their place, have a voice. We were stockpiling a lot of commercial parodies. You could feel something organically happening amongst us."[4]
Shuster's comedy legacy at SNL includes some of the show's most memorable characters and sketches from its early days, such as the beloved Killer Bees, and the Todd and Lisa sketch, played by Bill Murray and Gilda Radner. Radner's character of Roseanne Roseannadanna first appeared in a sketch by Shuster. Teaming up with Radner and writer Anne Beatts, she wrote the first sketches featuring Emily Litella, Radner's confused yet outspoken elderly woman, and Baba Wawa, her spoof of Barbara Walters.[5]
On SNL's social impact, Shuster noted, "You have to remember in the mid-seventies, there was Watergate and Vietnam. Rock music had broken out in the sixties as well as a lot of films like the Jack Nicholson kind of movies, Five Easy Pieces. They reflected the revolution in consciousness that came out of the sixties but television was still square as hell. So part of the impetus of the whole show was to just shake things up and to reflect back what was happening in the culture, the edginess and spontaneity that wasn't happening on television."[4]
During the eighties, Shuster helped Dana Carvey develop his recurring character the Church Lady, the uptight, smug, and pious host of Church Chat.[6] She also wrote a Tyrone sketch for Eddie Murphy which he performed when he was honored with the Mark Twain Award at the Kennedy Center.
