John Krasinski and Emily Blunt Pull off Christmas Super Prank.

For the past three or so years, John Krasinski (The Office) and Emily Blunt (The Five YearEngagement)have been pranking their neighbor. Now, their neighbor isn't just anyone. They live directly across the street from Jimmy Kimmel.

Let it be known that they are all really good friends and they've exchanged keys to each others houses So needless to say, they're close. Last year Jimmy got John and Emily REALLY good. He gift wrapped their whole house and made it snow...in California. It was up to John and Emily to get Jimmy back, and I think they've succeeded.
