Best-known episode: "The Money"
The 27-year-old Sarah Silverman had one season of Saturday Night Live under her belt, but she was still a relative unknown when she was cast as Kramer's girlfriend, the Jimmy-leg suffering Emily. Her restless leg syndrome causes Kramer to lose sleep, so he starts going back home after they have sex — only to change his mind when he thinks a cat burglar (actually Jerry's father, exercising in the hallway) is breaking into his apartment. When he tries to stay over at her place, though, Emily declines: "You're right, I sleep so much better alone," she explains. "And you scream in your sleep." Fortunately, Jerry's parents return to Florida, and Kramer and Emily find pre-marital bliss sleeping in their separate twin beds. CADY DRELL
