Nora: Um, Barney, what I'm about to say is going to sound a little weird, but I think I'm starting to like you, so I have to say it.
Barney: Well, for what it's worth, I'm not easily shocked. Unless you dump water on me, 'cause I'll just... [imitates electrical crackling] What is it?
Nora: I want to get married. I mean, not tonight, or even to you, necessarily. But that's what I want. And if that's going to scare you off, then I'd rather it scare you off now. [monitor: rhythmic beeping] I want a family, and I want to live in a little house with a garden and a tree for the kids to climb. [rapid beeping] And I want to go
to sleep every night with the same person by my side, and wake up next to him in the morning every morning [very rapid beeping] for the rest of our lives. [flatline] Just thought you should know that.
[Barney flashes back to Lily telling him not to lie to Nora]
Barney: That's exactly what I want, too.
[present: Lily slaps Barney in the face at the doctor's office]
