These people want to voluntarily have their legs/arms amputated just "because". One guy even went so far as to put both his legs in a bucket of dry ice for 6 hours and later when the flesh turned black the doctors had no choice but to amputate, which is what he wanted. He later said he regretted it at the end of the show because he was mentally ill at the time. Just when you think people cant get any more fucked up, a show like this happens.
