You know Curb Your Enthusiasm as a 38-time Emmy-nominated HBO comedy series — and maybe as a collective fever dream shared by everyone who ever watched Seinfeld — but it's also an unlikely wildlife documentary, devoted to the study of Larry David in his natural habitat. The Curb creator and star plays a misanthropic, fictionalized version of himself who operates on another plane of emotion, applying his unyielding moral code to every social encounter and sermonizing on the menaces of bald discrimination and the stop and chat (see also: the chat and cut).

But the hilarity of Curb emerges not only from its largely improvised dialogue — Larry is a maestro of his own face. All eight seasons of the long-running TV show will be released for streaming on Amazon Prime today. Before you binge-watch, consult our handy guide to the meaning behind David's every grimace, eyeroll, and sneer.
