But seriously, there’s no better movie in the franchise than Christmas Vacation. It has the best Cousin Eddie moments (“Shitter’s full,” “You serious Clark?”), as well as the “hap, hap, happiest Christmas” meltdown you’ll see anywhere. My wife and I make it a tradition each year to watch Christmas Vacation before anything else after we put up the tree and decorations. And when I ultimately get in over my head with the stress, anxiety, and tempered expectations of the holiday season, she makes sure to let me know that I’m acting like Clark.
