"He goes, 'Good, that's good. Now keep the time…' Like, stick to time," she continued, explaining that she went over her allotted three minutes. "I was going over the time… I wanted to tell my whole story."

"You gotta follow your voice," Saget affirmed. "One of the first things you said to me is 'I want to be like Richard [Pryor].' I said well okay, this minus some of the drugs ... but you had it in your heart. He was one of my mentors and one of my heroes and you know all of our heroes. You had the fire in you from the beginning."
