Oprah's Big Give heads to Miami, where host Nate Berkus introduces Joe and Gavin Maloof, the billionaire brothers who own the Sacramento Kings basketball team and the hip Las Vegas Palms Resort and Casino. "They live big, and trust me, they give big," Nate says.
"Gavin and I heard what you were doing," Joe says. "We wanted to be involved, so we brought you a little something." The "little" something? A briefcase filled with $700,000!
