List of Curb Your Enthusiasm recurring roles

Richard Lewis (as a fictionalized version of himself, Season 1–) is a neurotic stand-up comedian who has recently recovered from alcohol and drug problems. Richard is one of Larry's oldest and closest friends, both having moved from New York City to Los Angeles to pursue careers in comedy. Despite this, his relationship with Larry is often volatile and complicated. Often, Richard becomes the victim of Larry's follies, causing Richard to blame Larry for almost everything wrong in his life. He is usually more sensible and moral than Larry. He has also had numerous very attractive girlfriends over the course of the show, which Larry often tends to offend or clash with in some way. Richard Lewis first appeared in the show's first episode (after the pilot), "The Pants Tent".

Ted Danson (as a fictionalized version of himself, Seasons 1, 3–7, 9–10) is an old friend of Larry's despite the fact that Larry often insults him behind his back. When Cheryl and Larry separate, Ted chooses to side with Cheryl as the two often do charitable work with the NRDC. Danson often appears with his real life wife, Mary Steenburgen, who also plays a fictionalized version of herself. A sub-plot in season 9 involves Ted's separation from Mary, and his dating Cheryl, much to Larry's dismay. Ted invests in a restaurant with Larry and Jeff in season three, but he ends up leaving the project because he is upset with Larry. Larry and Ted constantly have problems exchanging gifts such as when Larry gives Ted a shirt with a hole in it, something Ted calls "a problem" rather than a gift. In the episode "The Freak Book”, Larry gives Ted a book titled Mondo Freaks, which offends Ted and Mary, then crashes Ted's birthday party by bringing his driver in, who gets drunk and harasses Mary. In "The Hot Towel”, Larry gives Ted and Mary a $300 gift certificate to a restaurant, but gets offended when he sees them using the gift certificate with Jeff and Susie instead of with him.

He has a wife, Nan, and one son, Joey, who is transgender and bisexual, as well as a sister with mental health issues named Bam Bam (Catherine O'Hara). He is often very methodical and by-the-book about most of his actions and puts much emphasis on family first, making sure the entire family takes one opinion on a certain matter. Despite that, he has been known to take credit for things which may or may not necessarily apply to him. Funkhouser is an avid golfer, golfing at the same country club as Larry and Jeff. Funkhouser first appeared in the fourth-season episode, "The Weatherman”. Uninvited, he turns up to Seinfeld reunion rehearsals, much to Larry's disdain, and befriends Jerry Seinfeld.

Larry blames Norm when he receives a reprimanded by the club for having a messy locker. Norm was the slowest golfer on the course, so others dreaded golfing behind him, until Larry, not knowing Norm had high blood pressure, yells at him and tells him off for his slow golfing.
