It's the most wonderful time of the year: Christmastime, or when John Krasinski pranks Jimmy Kimmel.

The actor, who is notoriously entwined in a decor war with the late-night host, revealed this year's stunt on Tuesday's episode of Jimmy Kimmel Live! with a proud smile.

"This is my greatest joy about this year's prank, is that we alternate, and I robbed you of the joy," said Krasinski. "And when I did the prank to you, I remember seeing your eyes saying, 'That's really funny — I hate you.'"

Krasinski first had a pants-less Santa Claus greet Kimmel at his office window with some snowfall, and then put a festively dressed reindeer in his dressing room. "That thing crapped all over my bathroom!" said Kimmel.

And while last Thursday's show taped, Krasinski had a crew re-create a North Pole scene in his office, with polar bears, presents and the actor as a life-size nutcracker.

"You went to great lengths, and I do have a little something for you," said Kimmel, as he showed Krasinski his flyers (posted all over town) for a "Celebrity Yard Sale."

But that wasn't all — Krasinski was then flooded with a slew of egg nog at his seat.
