74. Jeannie Steinman
Best-known episode: "The Invitations"
After Jeannie Steinman (played by Janeane Garofalo) saves Jerry's life, he discovers that she is his female counterpart, sharing all his obsessions from comic books to cereal. "Now I know what I've been looking for all these years: myself!" Jerry cries. "I've been waiting for me to come along, and now I've swept me off my feet!" They get engaged, but simultaneously break it off after Jerry realizes that "I can't be with someone like me — I hate myself!" GAVIN EDWARDS
