Larry David is an American actor and comedian who is probably best known as the co-creator (along with Jerry Seinfeld), executive producer, and frequent writer of Seinfeld. He was the inspiration for the character George Costanza. Many of the episodes stem from his personal experience doing stand-up and writing on Saturday Night Live and its early counterpart, Fridays, working with Michael Richards, Melanie Chartoff, and Bruce Mahler. At the end of Season Seven, Larry left, but he returned to write "The Finale". He did, however, voice certain characters in later seasons. After Seinfeld, he went on to create and star in another popular sitcom, Curb Your Enthusiasm. Larry makes many voice and appearing cameos in the shows throughout the series, most notably as the voice of George Steinbrenner. He also appears as Frank Costanza's Lawyer wearing a cape. Larry appeared in the first episode of Jerry Seinfeld's 2012 comedy web series Comedians in Cars Getting Coffee.
