Jerry is the main character from the TV series Seinfeld. He is loosely based off of Jerry Seinfeld the co-created and star of Seinfeld.
Jerry serves as the "leader" for his group of hopeless friends throughout the series
Jerry is the main character of Seinfeld and he serves as the straight man to the rest of the cast, typically offering up dry or quick replies and observations to point out how crazy his friends are. Actor Jerry Seinfeld's delivery in these moments was haled so much that this character was considered by many to be one of the greatest straight men in television history. However, even though his normalcy made him the "leader" of his group of wacky sidekicks ( Elaine, George, and Kramer) he still had his own quirks.
Throughout the series his obsession with cleanliness was a constant source of comedy, one girlfriend of his even going so far as to say "He'd make an excellent Nazi," because of his obsession with order. In fact Jerry's long line of ever changing girlfriends also served as a running gag, him having a new one in almost each episode and them breaking up for almost no reason. The only time he came close to a serious relationship was when he got engaged, only to have broken up with her at the beginning of the next season. His other most constant joke was his man-child like nature, him being obsessed with Superman and toys, in fact a Superman figure can be seen in his apartment on the shelves and a Superman statue is seen on his refrigerator.
