The 'pinky swear'

2 of 18

For this fantastic voyage, Oprah decided she wanted to take along her best friend, Gayle King. "I thought she'd be a perfect companion for this trip because we've been friends since I was 22 and she was 21," Oprah says. "But we never have been in close proximity for 11 days straight, 24/7."

What the friends didn't realize is that a cross-country trip can put a strain on even the best relationship. "People said doing this trip that we may not be speaking at the end of the trip," Gayle says to Oprah. "I don't believe that. Do you?"

Oprah and Gayle decided to not take any chances on the survival of their friendship! So, in the way that old friends do...they took a "pinky swear" oath.
