Christmas Vacation is a beloved holiday film, but an astonishing number of laws are broken and crimes committed throughout its 97-minute runtime. The struggles of Clark Griswold (Chevy Chase) to reconcile his idealized version of Christmas with the reality of unexpectedly hosting his dysfunctional extended family is a relatable one, even if the family antics are heightened to slight absurdity in Christmas Vacation. Everyone can empathize with Clark's desire to recreate the Christmas he remembers from his childhood, his struggles with his cheapskate boss shorting him a holiday bonus, and trying to maintain his patience with his less socially aware relatives.
