You never know when a Mistletoe may fall from the sky. A guy and a girl at Brigham Young University stood around with clipboards, asking people fake poll questions about the holidays . . . like, "Do you drink eggnog" and "Do you put up Christmas lights."  Then when they asked each person if they've ever kissed someone under the MISTLETOE, a string with mistletoe on it dropped down from above, so it was hanging right over them. Now, you'd ASSUME that most of the student body at BYU would be pretty conservative, since it's a religious school. But almost everyone in the video gave them a kiss. Except for one girl . . . who SLAPPED the guy and ran off.  Would you do it?
