Lloyd Braun was a recurring fictional character on Seinfeld. Braun grew up with the show's protagonist Jerry Seinfeld and his friend George Costanza. George's mother often pushed him to be more like Lloyd Braun, saying, "Why can't you be more like Lloyd Braun?" Lloyd is played first by actor Peter Keleghan ("The Non-Fat Yogurt"), then by actor Matt McCoy.
Lloyd suffered a nervous breakdown after his work on David Dinkins’ election campaign for Mayor of New York City was unsuccessful. He also dated, for a time, Jerry’s friend and former lover, Elaine Benes. It was Elaine who suggested the bad advice that may have led to the failed election campaign ("The Non-Fat Yogurt"). Following the Dinkins campaign, Lloyd spent time in an institution.
Following the breakdown Lloyd became very paranoid. He helped Jerry’s friend, Cosmo Kramer, in his attempt to gain historical status for a movie theater. He also helped hook Jerry up with a chewing gum supplier in Chinatown (getting him almost one hundred dollars worth of the stuff) and told Jerry and Kramer that Elaine should get herself a boyfriend when he caught her unfastening an antique button off movie historian Mr. Haarwood's shirt. Kramer stood up for Lloyd when a wise-cracking theater employee questioned Lloyd's sanity for wanting to eat a decomposing hot dog that appeared to have come from the silent movie era.("The Gum")
In the final season Lloyd worked for a short time for Costanza's father, Frank Costanza, selling computers. He was a disaster in that line of work, the phone having not been connected the entire time that he was supposedly "selling" computers. His warning to George to get his father to stop using the dangerous 'Serenity Now' relaxation technique fell on deaf ears("The Serenity Now").
