10 Actors Who Guest Starred On Seinfeld Before They Were Famous

Teri Hatcher played Sidra, yet another one of Jerry's girlfriends, on Season 4 Episode 19, "The Implant". Their relationship is fine until Elaine convinces Jerry that Sidra has breast implants. This freaks Jerry out so he sends Elaine on a mission to investigate. During this, she accidentally trips in a steam room and grabs Sidra's chest on the way down. When Sidra later meets Elaine again at Jerry's apartment, she assumes the fall was intentional and storms out.

Hatcher later got famous for starring in Lois and Clark and in Desperate Housewives. She also appeared as a Bond girl in Tomorrow Never Dies.
