Marshall: So, Gatsby, what are you gonna do when Robin shows up?
Ted: Okay, I got it all planned out.
[fantasy:]
Ted: [v.o.] She steps through the door, and where's Ted? Not eagerly waiting by the door. Nah, I'm across the room at my drafting table showing some foxy young thing all my cool architecture stuff. So Robin strolls over and I casually give her one of these, "Hey, what's up?" She says, "Hey, nice place" etcetera, etcetera. And then I say, "Well make yourself at home," and I casually return to my conversation. Then, an hour later, "Oh, you're still here?" I say like I don't really care, but it's a nice surprise. And then very casually, "Wanna see the roof?"
[fantasy ends:]
Lily and Marshall: The roof!
Ted: Get her up to the roof and the roof takes care of the rest.
