'Tis the season for John Krasinski [1] and Jimmy Kimmel's annual prank tradition, and this year, John and his wife, Emily Blunt [2], really brought their pranking game to a new level. Last year, Jimmy was behind an elaborate seven-hour prank that transformed John and Emily's house into Santa's village, and on Monday, the couple retaliated with a clever scheme of their own. When the late-night host went to hop into his car, he had a little surprise, and later, John rocked a Santa suit to bust some silly moves and prank him again. Watch the hilarious clip above, and then take a look at 35 times John Krasinski was just so damn adorable [3].
