Clark Griswold and his whole family absolutely cracks me up. Their National Lampoon's Christmas Vacation does me in every time. What a holiday classical.

Since 1989 National Lampoon's Christmas Vacation has been a classic. A instant classic if you will.  Chevy Chase is exactly how every dad is looked at in America. Not perfect but he means well. I watch it every year. Great Dysfunctional family Christmas movie.
