World's Smartest Kids

Quincy and DJ Casper take Oprah's stage to teach her a few moves from the "Cha-Cha Slide," a line dance with called instructions.

Texas viewers also join the dance party via satellite. Deborah Duncan, host of a morning news show in Houston, says the "Cha-Cha Slide" gets her viewers on their feet. "Dancing is really big down here with all the diversity here in Houston," she says. "We have everything from the two-step, and with the New Orleans influence, we've got zydeco."

Quincy leads Oprah and her audience through the moves. "When he says [get] funky, you get to freestyle," he says. "Do any cool moves you like to do."

After a few claps and foot stomps, Oprah gets the hang of it. "That is fun," she says. "Thank you, Quincy."
