Jimmy Kimmel and John Krasinski took their annual holiday prank war to a new level on Tuesday's episode of "Jimmy Kimmel Live."
Krasinski relished the fact that he pranked Kimmel not once, not twice, but three times this year already. It started with a Santa, who happened to not be wearing pants, getting hoisted up to the window of Kimmel's office. Krasinski kept things going by getting a live reindeer into Kimmel's private bathroom.

Krasinski's greatest prank, however, was turning Kimmel's office into a wintery wonderland with Krasinski disguised as a giant nutracker.
Kimmel found those pranks funny, but he took things up a notch. First, he posted flyers for a garage sale with Krasinski's picture and home address all over Los Angeles.
But Kimmel's sweet revenge took on a nog-like flavor when he dumped a big bucket of egg nog all over Krasinksi in front his studio audience.
