Seinfeld
Jerry’s dad, Morty Seinfeld, is one of the best parts of the show after his name. Barney Martin's performance as the father remains one of the most well-known of his career. However, the character of Morty was partially portrayed by actor Phil Bruns for the first season. He was recast because creators Jerry Seinfeld and Larry David thought the character should be grumpier and hard to please.
