Jimmy Kimmel has been in a holiday prank war with Emily Blunt and her husband, John Krasinski, for years now -- and this year was no exception.
"Oh no. What did John Krasinski do to me?" Jimmy Kimmel laughed on "Jimmy Kimmel Live."
Yes, Krasinski and Blunt filled Kimmel's car with ornaments then gift wrapped the entire vehicle while he was inside the studio.
Blunt and Krasinski's prank was an attempt to get Kimmel back for an elaborate stunt he pulled last year.
The late night host gift wrapped his famous neighbors' home last November -- yes, the entire house was covered in wrapping paper and bows and crawling with Christmas cheer.
Krasinski said he would never be able to top Kimmel's impressive (and expensive looking) prank, but gift wrapping someone's car is a pretty good start.
Blunt admitted later on Monday night's show that the car prank was both her and her husband's idea.
The naughty couple got such a kick out of gift wrapping Kimmel's car that they did it again the next day. You know what they say ... the couple that pranks together, stays together.
With antics like this, It's no wonder Blunt told Manhattan magazine her marriage is "an effing blast."
As for Kimmel, we're sure he's cooking up something big for next year. You're move, Jimmy.
