The Christmas spirit is already here, and Jimmy Kimmel marks the holiday with his famous four-year traditional prank on "Jimmy Kimmel Live. The funny host pranked actor John Krasinski again after exchanging pranks for the last four years.

On the latest episode of the hit late show on Tuesday, "The Office" star Krasinski ended up covered in eggnog. Time revealed that the pranks between the 36-year-old actor and the 48-year-old host have become a Christmas tradition, especially since the pranks were so funny and successfully orchestrated.

For this year, Krasinski planned and was successful in his pranks for the late night show host. First, he surprised Kimmel with a Santa Claus character outside his office's window, not wearing any underwear.

Then, Krasinski pulled off another prank, surprising Kimmel of a reindeer inside his office after yet another show that week. And to finally conclude Krasinski's set of pranks for the year, the actor decorated and basically transformed Kimmel's office into a winter and Christmas wonderland complete with all the polar bear statues and white blankets. When Kimmel entered, he was in shock as Krasinski leaped out of his costume to surprise the host even more.

The two pals talked about the pranks during the show without Krasinski's knowledge that he was about to be pranked at that exact time after Kimmel showed him a video of what he did to prank the actor. Apparently, Kimmel posted a yard sale announcement all over Los Angeles with the real address of the actor on them, and when Krasinski couldn't believe his eyes, eggnog suddenly dropped from the ceiling onto Krasinski's seat.

Meanwhile, Krasinski also appeared on the cover of Men's Health latest issue, showcasing his muscular body that he worked hard for to achieve. "I think there's a part of you where you become addicted to it," he told the magazine as quoted by Boston Globe.

"I love feeling strong. You pick up your daughter with ease while everyone else makes a little grunt when they pick up their kids. I walk with better posture and a little more presence. I was more of a sit-in-the-corner guy. Now I'm a lot less of that," Krasinski added.

Krasinski will be featured in the new Michael Bay-directed film "13 Hours: The Secret Soldiers of Benghazi," which will be released on Jan. 15, 2016.
