Richard Fish is one of only five characters to have appeared as a regular in all five seasons of the show. Richard Fish, has a very loose interpretation of both legal ethics and ethics governing interpersonal behavior and acts most of the time as though he has very little conscience, and thus tends to be far more comfortable than his friend John in social situations even when he said the most embarrassing things, such as suggesting to a woman interested in John that John was too nervous to begin a relationship, but that he, Richard, would be happy to have sex with her, but who was far more interested in making money than the technicalities of the practice of law, which he seemed to have little knowledge of. Of the partnership his friend John Cage was obviously a superior litigator, but due to John's social awkwardness Richard acts as the firm's public face. Richard's fellow lawyers often dreaded the prospect of Richard Fish appearing in court to argue a case although, several times during the show's run, Richard does a credible job in the courtroom, usually due to a combination of circumstances such as a sudden burst of inspiration or sheer luck. After his father is sued for sexual harassment his mother tells him he will never fall in love; he then declares his love for Liza. They marry at the end of the series.
