Barney: Sorry, I forgot my binocs for Foxy Boxing. Whoo, looks like things just got a little foxier right here.
Ted: Yes, they did. And you're just in time. Girls, I got to go, but I'm leaving you in very good, if slightly sullied hands.
Anna: Don't go. We don't even know your name to look out for your buildings.
Barney: Yeah, stay. [mouths "go"]
Ted: Excuse us for one second. [to Barney] Okay, you were right. The architect thing totally works. But I've got a girlfriend and I've got to get back to work. This project is getting harder and harder.
Barney: Yeah, you did.
Ted: Yeah, had to. See ya. [leaves]
Barney: [to Paula] Sorry, my, uh... intern had to leave.
Anna: Oh, well, that's too bad. I'm Anna, by the way.
Barney: Ted Mosby, Architect.
