No one would pass. Have you read the waiver? They can tattoo you, pull teeth out with no novocain, remove your nails from their nailbed, "use hypodermic needles" and dog shock collars, etc. and not be held liable.
$20,000 though, and the reputation of being the first guy to do it.
If they even have it. You'd assume they must, but there's no way they can't pull you out whenever they want.
Here is the "leaked" waiver, but I think it must be part of the experience. It says they can take your nails out, but the owner has said doing that is torture and that they totally don't torture people.
Can you really sign a contract that says it's okay to break your bones? I've only seen some footage, but they do try to feed you things until you puke, they cut your hair, shave it, your eyebrows, etc. It looked like they pulled a guys hair out by the roots, but it was hard to tell if that was real.
