Lawrence Gene David (born July 2, 1947) is an American comedian, writer, actor, and television producer, known for co-creating Seinfeld with Jerry Seinfeld, on which David was head writer and executive producer for the first seven seasons. Other work includes Curb Your Enthusiasm, which he created and stars in as a semi-fictionalized version of himself, Fridays, and writing briefly for Saturday Night Live.
In "Lois Comes Out of Her Shell", Stewie mentions that Sheldon without his shell is a "nude Larry David".
When Brian compares Stewie to Curb Your Enthusiasm's Larry David in "Stewie's First Word", the theme from that show, Luciano Michelini's "Frolic", can be heard.
Peter and Chris watch Curb Your Enthusiasm in "Supermarket Pete", with Jeff Garlin repeating everything Larry says.
