Best-known episodes: "The Susie"
Peggy (played by Megan Cole) is a designer at J. Peterman who is initially under the impression that Elaine is someone named Susie. As far as she's concerned, Elaine Benes is "that dolt" who "nearly ran the company into the ground." After Susie "dies" and Peggy realizes she's been talking to Elaine all along, she becomes convinced that Elaine is riddled with germs. In Season Nine's "The Apology," Peggy refuses to drink from a bottle of water that Elaine touched and uses a seat-protector in the ladies room, even though they're the only two women with access. She eventually explains that she's concerned that Elaine "seem[s] to be with a lot of men." JENNY ELISCU
