Grail hunters Rat Scabies and Christopher Dawes are selling a 2% equity share of the Grail - if they find it, that is - on ebay.Here's
a link to their site and book, Rat Scabies and the Holy Grail: Can a Punk Rock Legend Find What Monty Python Couldn't?
Of course, there is a contract involved. An excerpt:
(3) If the Holy Grail manifests itself as a cup or a chalice or a bowl or some other kind of vessel for holding liquid, it is hereby agreed that:
(i) The Grail Stakeholder will be allowed one sip from the vessel of a beverage of the Grail Stakeholder's choosing, which beverage to be provided by the Grail Stakeholder at the Grail Stakeholder's sole expense. The Grail Stakeholder may thereby gain eternal life and the healing of all physical ailments. However, because the Grail Finders cannot be held responsible for the mysterious powers of the Grail and all that, the Grail Finders shall not be held responsible for any failure on the part of the Holy Grail to give eternal life to the Grail Stakeholder, or to alleviate physical ailments, and the Grail Stakeholder hereby warrants to make no claims of any kind against the Grail Finders in the event of such failure.
