Lily: Barney, that woman you were talking to, our neighbor Geraldine, some guy slept with her and didn't call her, so she hunted him down and cut off a certain part of his anatomy with a cheese knife. So, whatever you do, don't sleep with her.
Barney: It's funny, she is, um, waiting for me in the guest bedroom right now.
Lily: Oh, God! Oh, God!
Barney: That was the idea, but now forget it!
