A Girl Scout troop leader suddenly came upon a clearing where a young couple was engaged in oral sex.
"Back ladies, back!" cried the leader. "There's a very dangerous beast out there!"
But it was too late, as several of her girls had more-or-less seen the deed happening. They asked their leader what it was the couple was doing.
"Well, err.... if you must know, uh, they were practicing a brand new form of artificial respiration... yeah, that's it, it's artificial respiration!"
"WOW!" exclaimed the oldest of the group. "I know which merit badge I'm gonna try for next!"
