Oprah Winfrey was asked the exact same question by every single guest she interviewed on her hugely successful talk show.
The 63-year-old revealed what was the question was during a panel at the Tribeca TV festival.
"Everybody that I ever interviewed, after every interview, at some point somebody would say,'How was that? Was that OK? How'd I do?" Oprah said.
"Whether it was Barack Obama or Beyonce or the guy who'd murdered his kids, the guy who had molested kids or somebody who'd ... lost their family, at the end of every interview somebody would say, 'Was that OK?'"

Oprah, who hosted 4,561 episodes of the talk show, added that when Beyonce asked her if she'd been OK she simply told the singer, "Girl, you're Beyonce!"
The TV icon also told the crowd at the panel that the success of the Oprah show was no accident.
"One of the reasons why the Oprah show was number one all those years is because we had intended for it to be so," she said.
The host would meet with the producers before every episode and would tell them, "Don't just give me a show idea, have an intention behind the show", she said.
