Quote from Rachel in The One with Joey's Dirty Day
Monica: How did it go last night? Rachel: Well, I didn't see Joshua. But I did punch a girl in the face. Phoebe: What? Why? Rachel: Well, the whole night was horrible. It was pouring down with rain. And when I got there there was no Rachel Green on the list. But there was a Rachel Greep. Phoebe: Wow. So did you get to meet her? Rachel: No, there is no Rachel Greep. But then this other girl overheard us. And she was all, "I'm Rachel Greep! I'm Rachel Greep!" And he let her right in. Monica: So you hit her in the face? Rachel: No, she was already in. But then this big bitch behind me tried to steal my umbrella, so I clocked her.
