Future Ted: [v.o.] Katie ended up having a great first time in New York. And the last thing we did before she left was go to the Empire State Building.
Ted: I am so glad we're finally doing this.
Barney: What are you talking about? We were here yesterday.
Marshall: Yeah, but that didn't really count. Oh, crap.
Lily: Exactly! So yesterday doesn't count as having gone to the Empire State Building. So I lost it to you, Marshall. And I rode that elevator to the top, and I saw that view, and I basked in the awesomeness. And that's our story.
Marshall: Yeah. Yeah, that's our story. We've only had sex with each other.
Lily: We've only had sex with each other.
Barney: They've only had sex with each other.
