In this exclusive clip, Krasinski picks his favorite prank that Jim has ever pulled on his office nemesis, and it's one of our favorites, too: the fitness orb debacle. The best part about the scene is there's a story behind the fall that some Office fans might not know about. After hearing it, you'll never look at the prank the same way again.
Check out the video below, and then head to the comments and tell us your favorite Jim-Dwight prank.
