The Susie

"The Susie" is the 149th episode of the sitcom "Seinfeld". This was the 15th episode for the eighth season. It aired on February 13, 1997.
Plot.
Kramer's friend Mike has become a bookie. Kramer, a compulsive gambler, places bets with Mike on Jerry's behalf. But when Jerry wins, Mike can't pay up. When Jerry accidentally slams his trunk lid on Mike's thumbs, breaking them, Mike becomes afraid of him. Mike tries to make up his debt by fixing Jerry's trunk but gets trapped inside.
Kramer sets his watch ahead one hour even though Daylight Saving Time hasn't started yet. Elaine's co-worker Peggy calls Elaine "Susie," but Elaine neglects to correct her. However, when Peggy later addresses her as "Suze," she vehemently objects to the use of any diminutive. Peggy complains to Peterman about the rude outburst, and he arranges a meeting between Peggy, Elaine, and "Susie." At the meeting, Elaine manages to simultaneously pretend that she is Susie to Peggy and that she is Elaine to Peterman, but Peterman then begins giving "Susie" her own assignments. While driving Elaine, Jerry recognizes that her charade has gone too far and tells her she should "eliminate Susie." Mike, still trapped, overhears and interprets this to mean murder.
George is excited about Steinbrenner's ball because he wants to make a grand entrance with his girlfriend Allison with her wearing a backless dress. Allison tells George, "We need to talk." He goes to great lengths to avoid her so that she can't break up with him. She finally resorts to using Kramer as a go-between, and Kramer breaks up with George on her behalf. George tries in turn to use Kramer as a go-between for making up with Allison, but she refuses, and Kramer shows up at the ball in her place. During a scuffle in the lobby, George tears off the back of Kramer's tuxedo, and Kramer is thrown into the main hall, making a (backless) "grand entrance" of his own.
Elaine tells Peterman that Susie committed suicide, so Peterman organizes a memorial service. Elaine and Jerry attend. When he arrives, Peterman rear-ends Jerry's car, inadvertently freeing Mike. Peggy is confused to see "Susie" at the service, so Elaine belatedly corrects her about her name. Mike bursts in and accuses Jerry of murdering Susie.
Peterman proposes establishing a foundation in Susie's honor, so Elaine finally tells him the truth. However, he misunderstands and expects Elaine to devote all of her non-working hours to running the foundation.
Production.
The impetus for the episode's story was when one of writer David Mandel's co-workers on "Saturday Night Live" called him the wrong name. Mandel didn't correct him, so he continued to call Mandel by this name for their entire time together on the show. Mandel said he was struck by the fact that there was no one on "Saturday Night Live" with that name that he knew of, inspiring "The Susie"'s core idea of a misremembered name leading to a belief in a non-existent person.
George's answering machine message, a George-sung parody of "Theme from The Greatest American Hero (Believe It or Not)", was also based on real-life events. A friend of a friend of Mandel's used this same parody for her answering machine message. Since actor Jason Alexander is a good singer in real life, he was told to sing as poorly as he could after his first take of the song was judged too good to be funny.
Mandel later said he considers "The Susie" one of the weakest TV episodes he has written, feeling that the bookie plotline didn't go anywhere.
