Someone on my floor put a giant (6-foot tall) poster of Faith Hill up in their window. It was a moderately suggestive pose, but not tasteless (don't judge). One night, the dorm mother started throwing rocks at his second floor window, yelling for him to come outside. The RA opened up the door and dragged him down for the "come to Jesus" talk. The Faith Hill poster was removed.
When the same student passed around a petition amongst his floormates to hang said poster back up (the reasoning was "How can you not have FAITH, at BYU?!"), the student was punished again.
Come to think of it, I don't know if I ever got that poster back....
