Trivia: Newman's appearance in the episode is an obvious reference to Harvey Keitel's character The Wolf in "Pulp Fiction". Before Newman arrives, Elaine mentions that he "makes problems go away" just like The Wolf. Newman even uses the same "If I'm curt" line.
Trivia: Throughout the entire show, a Superman figure can be seen on the shelf in Jerry's apartment. When Elaine goes to "Bizarro Jerry"'s apartment, a figure of Bizarro can be seen standing on the cabinet.
