Jimmy Kimmel gets pranked by Emily Blunt and John Krasinski

Looks like the epic but innocent Christmas prank war continues on as Jimmy Kimmel gets pranked by his neighbors, Emily Blunt and John Krasinski.

The tradition began three years ago when the couple pranked the late night host by "breaking" in to his house using the extra key he gave them and left a light-up Santa and snowman in the home. Kimmel and his wife, Molly, then returned the favor by installing a large neon insurance sign on their driveway. Little did they know that it will be an annual tradition from that day on. Last year was Kimmel's turn where he pranked the two with a 40-foot inflatable reindeer (that came with a non-inflatable reindeer poop) making it Blunt and Krasinski's turn to flip things over.

Shortly after his taping, the late-night show host found his SUV covered in wrapping paper and stuffed with festive ornaments at the parking lot and a tag on the side that read "From your secret Santa". But it does not stop there as the two topped the prank up with carolers that sang Christmas songs like Deck the Halls, Hark! The Herald Angels Sing and We Wish You A Merry Christmas with one of them bringing a reindeer and extra wrapping paper. Then, the prank was further topped with Krasinki taking the SUV for one last spin while going as a two-bearded Santa. The whole thing was caught on video.

Blunt shared at Kimmel's show on how they came up with the idea during her promotion of her upcoming movie, Into The Woods.  "We went through a couple of options and just decided to do all of them," E! quotes.

Looks like Kimmel's on his run for his money this time. Will he top that great prank off with another brilliant prank? Only time will tell.
