Already a smash hit in the UK and most recently awarded a BAFTA, the UK’s most prestigious television award, WIFE SWAP gives two families the rare opportunity to witness what it is like to live someone else’s life and experiences. Two matriarchs from two households trade places for 10 days. For the first five days of the challenge, they must obey the rules of the new family’s lifestyle and adopt their daily routine – parenting, shopping, housework, creating budgets and social life. For the remaining five days, these women get to run the new house their own way – a radical shock to both families. This intense new series taps into America’s voyeuristic tendencies and desires to judge how others run their households, raise their children and treat their spouses. Never before has a reality series taken such an honest inside look at the American family.
Here is a link to the original British show's site, on Channel 4. There's a note at the bottom of that page that "Wife Swap is going international" -- so I guess there's the potential that someone here in the US could end up swapping with someone in the UK.
