Lily: New girl? What new girl?
Barney: Two girls are allegedly vying for Ted's affections and I think...
Lily: Oh, you don't know what you're talking about. Give it to me. [takes Barney's cell phone and talks to Ted] Are they friends?
Ted: Yeah. No, I don't know. They're old sorority sisters.
Lily: Are they Betas? Because they're all sluts and you can tell them right now I didn't wanna be in their sorority anyway.
