AFTER FIVE YEARS AND 198 FAMILIES, "WIFE SWAP" CELEBRATES ITS 100TH EPISODE BY SWAPPING TWO FAN FAVORITES FROM PAST EPISODES IN A TOTALLY NEW SWAP

"Wife Swap," the critically-acclaimed unscripted reality show that takes us into the intimate heart of the American family home, premiered in the United States in 2004. In the show, two very different families take part in a two-week long challenge: the wives exchange husbands, children and lives (but not bedrooms) to discover what it's like to live in another woman's shoes. From city dwellers to country folk, from clowns to pirates, 198 remarkable families from across the U.S. have participated in this mind-blowing experiment and seen their lives changed forever.

In October 2008, ABC asked viewers to help celebrate the 100th episode by voting for favorite families from past episodes whom they'd like to see swap lives again. From a pool of 24 past families, ABC viewers from across the country went to ABC.com and picked their favorite four families. Now it's finally time to announce which two families were chosen by the producers to participate in the 100th episode's ultimate "Wife Swap":

The families that have been chosen for the 100th episode swap are the storm-chasing, science-obsessed Heene family from Colorado and the psychic, performing arts-loving Silvers from Florida.

When the Heene family aren't chasing storms, they devote their time to scientific experiments that include looking for extraterrestrials and building a research-gathering flying saucer to send into the eye of the storm. In this ultimate swap, the Heenes swap lives with a psychic mom who speaks to the dead and can control the weather, her husband and her children -- who believe they are destined to be stars. This show will feature aliens, punk rockers, past-life regression and, for the first time ever, the children from the two families will face off in a kids' table meeting. "Heene/Silver," the 100th episode of "Wife Swap," destined to become a classic, airs FRIDAY, MARCH 13 (8:00-9:00 p.m., ET) on the ABC Television Network.
