Fun thread...all this talk about the Holy Grail had me thinking of Indian Jones and Last Crusade...I know this is geeky, but remember at the end when they have to choose the grail among a whole collection of goblets? The fancy one turned the guy to dust! And it was the plain cup of the carpenter that was the real grail!

Anyways, so the real grail should be both rare and functional...not just fancy :P Nah, well, I understand though, just a fun topic for discussion
