A haunted house that promises an extreme experience that can last up to 10 hours requires participants be medically cleared by a doctor and sign a 40-page waiver.

The McKamey Manor experiences in Summertown, Tennessee, and Huntsville, Alabama, also require visitors be at least 18, insured, and pass a background check and drug test.

FOX 17 News reported on a story last year when neighbors, county officials were upset after the extreme haunted house opens for business in their area. Last year, there was a report of a woman being kidnapped. Police arrived and found a woman shivering beaten and duct taped in a cellar.

But guess what; she signed up for it.

A local news station reports that owner Russ McKamey offers thousands of dollars to anyone who completes the tour, but says no one ever has. He records each tour on video -- for his own protection he says -- and then posts them online , showing them quitting in humiliation.

It's costs nearly nothing to enter: Just a bag of dog food. The website warns of physically demanding environments, but McKamey says the manor is a mental game.

The haunted house has a 40-page waiver.

On that waiver it says you agree to being shocked, submerged in water, slapped, tied up, shaved or even unwanted dental work.

Only one person is allowed on a tour. It can last for hours, although McKamey says it never does.

?In 16 years, not one person has been able to get through it without saying 'I'm done',? McKamey previously said to FOX 17 News.
