The virgin would be put inside a wicker man(or wicker cage if the man wasn't big enough). They were each given a choice to take a chance as to whether they would be allowed to escape. If someone accepted, that person would have one try to grab an apple with her teeth -- from a vat of boiling cider-like substance. Failure meant death on the spot; success meant going free... with damage from the boiling water. Any who declined a bid for freedom would be burned in their cages.

Yeah. And then they went and made Michael Meyers! I think that was because their pentagram nonsense wasn't really very effective altogether. So they went for knife-wielding maniac instead.

Personally, I think that's a better way to extort virgins altogether.
