I love Wife Swap. :D One of my favourite things about it is how it clearly shows how horrible some families are -- and more often than not, it's the 'conservative Christian family' that ends up looking like shit.
Those Baptists got smacked the fuck down. And it's always the 'fucked up family' that embraces rule changes & actually learns from the experience, when you would actually expect it to be the other way around.
And the final confrontation! That guy was such a fucking asshole, and, despite all his wife said she learned during the Swap, she just let him drag her out of there.
