[AA] Throwing a Paper Airplane Sends a Happy Sim into Hysterics

Sometimes Sims automatically start throwing paper airplanes (I don't know where they get them from, as I don't make them myself). When a Sim has a lot of "happy" moodlets, they all shift into a "playful" state, which then sends the Sim into hysterics, which can lead to death by laughter.
