Here in the UK we have the Jeremy Kyle show, a slightly sanitised version. It features a small, obnoxious, immensely arrogant host berating, insulting and generally belittling the "guests" whose issues generally involve an inability to control their genitalia.
Personally, I think they find the guests by throwing a big net over a Lidl, (or Wal-Mart, I guess) and dragging the pond life out.
