I hate reality shows. That said, this one episode is an absolute gem. They put a mother who's a close minded obsessive Christian (the bad kind) in a family who were "new age." The father had a radio show where he talked about reading fortunes (the co-host was gay and it really freaked her out). She refused to even listen to anything they ever said.
At the end of the show, when she returned to her family (who loved the open minded and kind mother from the new age family), she had a break down and freaked out. It was one of the funniest TV moments ever. The ending is the funniest part, too.
