He’s the kind of guy that’s known for setting unrealistic expectations on almost everything he does, he’s even called “the last family man” by his co-workers. That man is Clark Griswold (Chevy Chase), a high-level food additive executive who insists on having Christmas at his house alongside every living relative in his family, in-law or otherwise. Due the utter chaos that such a large gathering of people under one roof during the most stressful time of the year will bring, National Lampoon’s Christmas Vacation (which is a part of the Warner Bros. Holiday Gift Guide) is a testament to not only family, but to how much one man can take during the holidays. Though, to be fair, it’s not like Clark doesn’t let out a little steam here and there with a well placed barb at his family’s expense. And those are the real present to us, the viewer. So, start the drum roll, here are Clark Griswold’s lines that you wish you could use on your own relatives when the holidays roll around.
