Larry David

Curb Your Enthusiasm makes a fictional version of David argue over the unwritten rules of ordinary interaction. Seating, greetings and small obligations become conflicts because he insists on making the usually unspoken negotiation explicit. HBO's social-etiquette clips offer a concise introduction. Watch how his attempt to clarify a rule creates another problem with the person in front of him. The humour depends on that escalation and on a performed character, not on assuming every scene documents the creator's private behaviour.
