WATCH: Kate McKinnon, Jason Bateman, T.J. Miller and More Get Merry in ‘Office Christmas Party’ Trailer 

Jennifer Aniston Tears Up When Asked About Self-Doubt
The TV star got emotional during a recent Q&A.

A hilarious premise, an insanely talented cast and a partridge in a pear tree.

Although huge swaths of the U.S. are fending off heat waves at the moment, the trailer for the new comedy Office Christmas Party will have you singing carols and craving some spiked punch (and maybe a clandestine rendezvous in the supply closet).

Although CEO Carol Vanstone (Jennifer Aniston) wants to put a stop to her brother’s (T.J. Miller) booze-loving branch, he and Josh (Jason Bateman) need to throw the end-all Christmas party in order to close a sale and save their jobs.

The clip includes co-workers jousting with lit Christmas trees, a vending machine getting pushed out a window, a reindeer drinking from a toilet and ugly sweaters, obviously.

But Kate McKinnon’s Rite Aid line is a new classic.

Enjoy the raucous revelry above.
