You gain 4 additional girlfriends once you stop playing WoW. It is statistically proven that WoW equals 4 girlfriends. No one exactly know where they come from, but WoW is the only thing that prevents the world from being flooded with insane amounts of girls.
Actually, that is the sole reason we even play WoW. We simply could not stand all those girlfriends jumping at you at every corner of the street if we didn´t.
