At first I thought I would find this offensive...
But it portrays an important point about cultural respect. It is extremely disrespectful to take any lava rocks from any Hawaiian volcano (the equivalent of me painting googly eyes on a picture of Christ in a Christain church). As to the stories about the curse, technically they are true. It actually stems from a certain parasite hidden within the rock that can make you sick (and kill in smaller animals like cats or fish). Most people attribute it to the curse of Pele, but scientifically speaking, it's because of a parasite :P
