This Christmas, Dwight finally has the chance to get Jim's goat. Needless to say, it involves disguises, trickery, and cold-blooded cunning.

At first, we see an uncharacteristically blunt snowball attack on Dwight. Jim's lack of witty vision in his prank? Disconcerting. And it is clue 1 as to why he is not ready for what's to come.

Dwight responds with a brilliant ambush of his own.

And just to lay it on thick, Dwight uses one of his many office wigs pull another fast one.

At the end of this holly jolly day, Jim is left a twitching mass of nerves, and Dwight bests him with one last, intricate, terrifying prank. What a good reason for Christmas cheer.
