As with "Seinfeld", which David co-created, the humor of "Curb Your Enthusiasm" often revolves around the minutiae of American daily social life. Episodes frequently center on Larry's ignorance of or disregard for well-established social conventions and expectations, as well as his insistence that others adhere to rules of which only he seems to be aware. This social ineptitude, combined with his inability to let even the most minor grievance or annoyance go unexpressed, often leads David into awkward social situations and draws the ire of his friends, family, and total strangers. Larry is also routinely the victim of elaborate misunderstandings. Each episode's plot and subplot is established in an outline written by David, and the dialogue is largely improvised by the actors (a technique known as retroscripting).
