Ah, Christmas! Tis the season for mistletoe, holly, shopping, and the career-derailing office Holiday party. Between online shopping, giving out Secret Santa presents, and wandering from cubicle to cubicle snagging holiday cookies, not a lot of work is getting done this week across America, and the annual office gathering puts the icing on the anti-productivity cake. Woo hoo! But it’s not always peace on earth and goodwill toward men.

Is it really considered a party when the boss celebrates by telling everyone they have to work extra late on Christmas Eve and then staples antlers onto a mouse’s head? Frank Cross (Bill Murray) is such a boss and he hosts easily the worst office Christmas “party” ever, until the ghosts of Christmas Past, Present, and Future show him the error of his ways. And he still manages to make it even more awkward with a shotgun-wielding assistant and half-crazed 10-minute monologue broadcast live on national TV. Mood swing, much?

Hey, here’s a question for all you Christmastime gourmets out there: How does one poach a smoked salmon? If you’re newly-impoverished Skeevy Claus Louis Winthorpe III (Dan Aykroyd), you shove it down the front of your shabby Santa suit, and you chase it with as much champagne as you can guzzle (hey, it’s a long bus ride back to the ghetto). And what goes with contraband fish? Bits of fake beard and Santa coat lint, of course! Don’t forget to take your big bag of drugs to the executive suite and try to frame your successor. One side note though, since this movie took place in the 1980s, did he really need to bring the drugs with him?

Okay, this one might be a stretch, but if you consider being the King of England a job (and at one time it did contain more duties than waving and dodging paparazzi), then it counts. Even the most dysfunctional modern family or office environment doesn’t have as much murderous duplicity, witty banter, and seething rage as the court of King Henry II (Peter O’Toole). He brings his three sons, his imprisoned wife Eleanor of Aquitaine (Katherine Hepburn), his mistress and presumed future Queen (Jane Merrow), and King Philip of France (Timothy Dalton) together to celebrate Christmas in 1138, and, they all hope, to solve the question of succession once he’s gone. What he does decide, after all the murder plots and secret alliances, is that he mostly hates all his kids, and he doesn’t really want any of them taking over the family business, which happens to be running England. Kinda puts the snide comments of passive-aggressive in-laws in perspective, huh?
