Oprah Winfrey on '30 Rock'

Last season on NBC's 30 Rock, Liz Lemon (Tina Fey) had a once-in-a-lifetime experience that most people only dream about: sitting next to Oprah Winfrey on a plane. The queen of self-help talk tolerated Liz -- barely -- as she unloaded her emotional issues and asked for guidance. "You are the best person in the whole world," Liz tells her, and passes out completely. As it turned out, it was a dream—thanks to in-flight medication that Jack (Alec Baldwin) advised her to take. Back at the office, Liz told her friends Oprah "smells like rosewater and warm laundry," and that the world-famous TV host agreed to drop by to help Jenna (Jane Krakowski) and Tracy (Tracy Morgan) work out a conflict. But Oprah wasn't really Oprah: When she shows up, Liz's seatmate is actually a chatty tween -- who did a surprisingly good job mediating the feud.
