Oprah's Funniest Moment At Miraval

Over the next few weeks, keep your eye out for "The Oprah Winfrey Show" set at Miraval , Oprah's favorite destination spa. Oprah went to the Arizona spa to get healthy and challenge her life with her best friend Gayle King and 60 other women -- 50 who won an O, The Oprah Magazine contest by writing letters saying why they deserved a spa vacation, and 10 who won an Oprah.com sweepstakes. A PR insider tells me it's supposed to air in the next couple of weeks, and she'll let me know the exact date the moment she knows it.

Oprah has already said on her website that one of the funniest moments of the trip happened when she and Gayle decided to try an exercise called "A Swing and A Prayer" on a challenge course. "They attach you to a cable and then they pull you up 40 feet in the air, and then it's up to you to decide when to let go. And you swing like a pendulum back and forth," Oprah says.

Oprah went first, but when Gayle got up in the air, she nearly had a "nervous breakdown." "It's going to feel like a roller coaster, that's all," Oprah tells Gayle. "I hate roller coasters," Gayle says, clinging to the rope.

Oprah says she couldn't help but laugh. "I laughed till I almost peed on myself," she says. "Then I realized she was really, really, really scared. I still kept laughing."
