Why someone would ever buy something like this?
Probably the same reason I would: I like things with a story behind it.
Just imagine the conversation between you and one of your friends about it! It would probably go something like this: "Yoyoyoyo, what is this thang doin right 'ere on your shelf!" "Well, you see. I got that high up in the mountains of Honolulu. It was encased in ice and I slowly chipped it out."
Even if this explanation is completely irrelevant and clearly false, it made a hell of a story right?
