December 25 is National Jews Go to the Movies Day.

Stewart’s line riffs on a well-known American Jewish cultural habit: because Christmas Day is a major Christian family holiday and many businesses close, Jewish families—who typically do not celebrate Christmas religiously—have historically found movies (and often Chinese food) to be among the few widely available public activities. By mock-officially dubbing December 25 “National Jews Go to the Movies Day,” the joke highlights both outsider status and assimilation: it turns a minor, practical tradition into a tongue-in-cheek “holiday,” using humor to acknowledge difference without bitterness. It also satirizes the American tendency to label everything a “national day,” treating cultural quirks as civic observances.
