Some twenty some odd years ago - we had three "priests" in the stake go up to girls camp in their own car around midnight. Donning masks, and carrying axes, they began breaking down the doors to the individual cabins - coming in - screaming that they were going to "harm" every last one of them. It was so fun for the boys - that this went on for a whole twenty minutes while they laughed and busted down a dozen doors, running around camp with axes, scaring everyone to death. The girls were traumatized beyond belief - and counseling was provided afterwards. The female leaders were scared to death being unprepared for ax wielding perps being unable, or willing, to protect their charges. This was way way up in the hills with no reception, and the only phone was in the kitchen lodge far away from the individual cabins. The prank was so good - our stake leaders still talk about it every year, and every night of girls camp since then, a "two man" priesthood team night patrols, and spark the air with walkie-talkies, providing security and comfort to the young ladies.
