Toward the end of the piece, they mentioned a newer trend toward people converting their basements into elaborate dungeons/puzzles and people paying to stay there - with the only way out being that they have to escape. I don't know much more than that, although from the sounds of it, it sounded like something out of Saw or Hostel.
I'd say that it can be chalked up in the "people are weird" column - except that I'm talking to the Idol audience, who are pretty much the spokespeople for the "people are weird" movement! ;)
