[flashback to Ted and Marshall in their college dorm room:]
Ted: And who knows, by then, you and Lily might be engaged.
Marshall: Engaged? Bro, I'm gonna do way better than that.
[fantasy scene as Ted & Marshall imagine what 2003 will look like:]
Lily: Ah, being pregnant is so much fun. I want to do this four more times.
Marshall: Oh, baby, how do you feel after spending all day working on your art, since I make enough to support us both financially?
Lily: Horny. I hope we don't bother you, Ted, because even though we're married and pregnant, it still makes sense that we all share adult-sized bunk beds.
Ted: So, Star Wars?
Marshall: Sure, I don't have to be at work until late afternoon-ish because my boss appreciates that I like to stay up late drinking and rocking out with our band.
Robin: [enters] Did someone say rocking out?
[college:]
Marshall: Whoa, who's the babe?
Ted: That's the best part.
[fantasy:]
Ted: Guys, you remember my awesome girlfriend who was a virgin until we met?
Robin: My name's Rhiannon, like the Stevie Nicks song. I'm hot, but in a crunchy, earthy kind of way. [British accent] Oh, and I'm from England.
Marshall: Nice. Okay, Star Wars time. But first, we jam.
Ted: Good thing I spent the last three years learning to wail on guitar.
