Oprah Katrina Homes

In Houston, families thought they had gathered to interview for a Habitat for Humanity home, but little did they know, Oprah was backstage with a big announcement.

"I want you to look around at all the people that are here, because you might have come in with people who were strangers, but I want you to know that as of today, you will all become neighbors," Oprah said. "Every family here is getting a new Habitat home—nobody deserves it more than everybody in this room."

Along with Houston's mayor, Bill White, Oprah passed out toolboxes so the families could begin building their new community from the ground up. As a down payment, the families pledged to work with Habitat for Humanity volunteers for 300 hours on the construction of their new homes.
