 I only want to play girls because I don't want to be embarrassed. I would not do the tour. I wouldn't do Billie Jean any justice. So, Andy, stop it. I'm not going to let you kill me. That's Serena Williams telling Letterman I would never play Andy Murray. He would kill me. He would humiliate me. She's the best female tennis player who's ever played the game. I mean, dude. That's true. That is true. But stupid people have co-opted this narrative that men aren't better than women.
