I never realized that normally happy go lucky Clark Griswold really has an edge to him in many of these scenes in 'National Lampoon's Christmas Vacation'. Since nobody is left at your workplace anyway, crank this NSFW up LOUD.

I always thought my favorite scene was Uncle Lewis asking Clark to 'Get me my stogie', now I think Clark's meltdown with the egg nog is the new champion scene of this John Hughes classic.
