Wife Swap takes opposite lives then switches them for two weeks. City meets country, strict meets lenient, animal-lover meets animal-hater.

Lynn Bradley, meet Jodi Spolansky (10 p.m. today, Channels 9, 22).

Bradley lives in rural New Jersey and drives a school bus, gardens and does housework. She's also a wood crafter. With her husband, she raises two daughters (13 and 12) and runs a firewood business. She says she was ready to swap lives with anyone.

Spolansky, on the other hand, is a multimillionaire, lives in Manhattan and doesn't have a job. Before the show, she spent an hour a day with her kids, ages 7, 6 and 2. After all, she has four nannies to do that.

She also works out, and spends her days at salons, lunching with friends and shopping.

They swapped lives for two weeks in a show that puts a spotlight on how people live. This isn't Trading Spouses, the Fox knock-off. ABC's show is based on a British hit, with the same people, Stephen Lambert and Jenny Crowther, producing.

During the first week, the wives must live by each other's rules, covering everything from budgeting and parenting to socializing and shopping. But during the second week, they can run their new households however they see fit.

The contrasts come in all forms. In today's hour, that involves money. Spolansky and her husband (who owns an importing company) have a lot of it; Bradley and her husband (who clears lots) have some.

And yes, people change.

Spolansky says she's not really the me-centered person viewers see. She has held jobs in the past. She now spends more time with the kids.

Bradley emerged from her Manhattan adventure with a layered hair cut from Spolansky's stylist ($500 for the cut, $65 for upkeep) and a husband who has seen the difference in wives and lives.

"He's been helping me out around the house," she says. "He appreciates me a lot more."
