[As Ted watches the pornographic movie "Archisexture", from Barney's collection:]
Woman: [on tape] Archisexture...
Barney: [on tape] Hello, Ted. If you're watching this tape, and I knew you'd pick this one, then you are now in possession of my porn. This can only mean one of two things, either I'm dead, or I'm in a committed relationship. If I'm dead, I want you to honor my memory by taking my body to The Hamptons and recreating Weekend at Bernie's. I wanna dance, I wanna have sex with a girl and I wanna go fishing. If, on the other hand, I'm in a committed relationship, then, as your best friend, I have only one request. Please, for the love of God, get me out of it!

[flashback to Barney and Robin fighting the "Canadian-American war":]
Barney: Thank God that song's over. Who the hell was that old lady singing?
Robin: Okay, you know that Neil Young is my favorite musician.
Barney: Right. Now was that the same old lady who played Archie Bunker's wife in All in the Family, or just a sound-alike?
Robin: Neil Young is a Canadian treasure. Do not make fun of Neil Young.
Barney: Robin, I would never make fun of a defenseless, old lady with vocal cord paralysis. Ever.

Lily: Are you out of your mind? You knew they were playing relationship chicken, and what did you do? You put an engagement ring in front of them. Okay. That's it. I'm taking over. I'm coming out of retirement for one last breakup.
Ted: Yes!
Marshall: All right. How are we gonna do it?
Lily: These guys are in so deep just one fight ain't gonna do it. We need to reignite the four biggest fights they've ever been in, all at once. Number one, the battle of the dirty dishes. [flashback to fight] Number two, the ex-girlfriend conflict. Number three, the Star Wars altercation. And of course, the biggie, the Canadian-American war.

Ted: I got it. I got it. We e-mail them pictures reminding them of each of these fights.
Lily: You child. Here's how it goes down. They're at the diner. First, rekindling the Canadian-American debate... Ontario native Alan Thicke stops by the table.
Marshall: Whoa, whoa, whoa.
Ted: Alan Thicke?
Marshall: Oh! Right, Robin knew him back when she was a singer.
Lily: Yeah, and they still keep in touch. I already got his number off her phone. Seriously, amateurs. [.vo.] So Alan Thicke restarts the Canada-US fight. Right at that moment, Crazy Meg shows up. Then, a Stormtrooper happens to walk by the window. And just when they can't take anything more, a busboy walks by with a tray full of what? Dirty dishes.

Alan Thicke: Well, Robin, I'm glad we could catch up.
Robin: Yeah. Let's do it again soon.
Lily: I love that you guys are still friends so long after you did that music video.
Robin: Yeah.
Alan Thicke: The music... Oh, the Sandcastles video. Yes, yes. We did that together, too.
Barney: What do you mean "too"?
Alan Thicke: Well, we had this failed Canadian TV variety show. That was so embarrassing. Imagine what would happen if anybody ever got their hands on that?
Robin: Oh, you.
[Barney runs out of MacLaren's]

Pizza guy: Someone ordered an extra-large sausage.
Ted: Hey, one of Barney's videos starts off just like that.
Marshall: Hey, guys, Barney's ordering five of something.
Pizza guy: I don't know if it's gonna fit in here.
Ted: Okay. Now you're just quoting the video.

Future Ted: [v.o.] Kids, as long as I'd known your Uncle Barney, he'd always had some pretty strong opinions on relationships.
[flashback to Ted with a woman and the gang at MacLaren's:]
Barney: Your girlfriend? She's your "girlfriend"? She's a girl, and a friend? How is... Do not humanize the enemy, Ted. But nice to meet you, Barney Stinson.
Future Ted: And yet, in the fall of 2009, he was the one with the girlfriend.
[the gang in the apartment:]
Barney: Go ahead, open it. Open it, open it, open it, open it! It's my porn collection! Just kidding. That would be weird.
Ted: It's your porn collection.
Barney: It's my porn collection! I'm giving you my porn. Now that things are so great with Robin, I don't need it anymore.
Lily: Wow. You are voluntarily... [Barney nods, Robin shakes her head] giving up your porn.

Ted: You know, in a way, it's sad, right? I mean, Barney's giving up his porn. He's got relationship gut. They eat at the same diner every night. It's like the end of Barney Stinson as we know him.
[Marshall and Lily each grab a porn DVD and try to sneak it out of the apartment]
Marshall: Yeah, well, so what? They're happy...
Lily: Yeah, well, we gotta go. Later.
[in the hallway:]
Marshall: So, what'd you get?
Lily: I got Squat.
Marshall: What are you... I thought I saw you take one?
Lily: Yeah, I did. It's called Squat.

Ted: Look, there's no reason we should take this seriously, right?
Lily: Of course not. This is an old tape. Barney is happy with Robin.
Future Ted: [v.o.] But over the next couple of weeks, I started to notice things. Barney and Robin stopped having crazy adventures.
[at MacLaren's, where Barney is eating bar nuts throughout the conversation:]
Lily: So, what'd you guys do last night?
Robin: I wanted to go to a concert. He wanted to go to a party. Obviously, we couldn't do what just one of us wanted, so we just stayed in, watched a movie on cable.
Barney: It was Legen... Wait for it. ...ds of the Fall. Legends of the Fall! It was okay.

Marshall: You're right. Barney and Robin are miserable together, but they're too stubborn to admit it.
Ted: So, we have to get them to break up.
Marshall: How do we do that? We unleash the Kraken.
Future Ted: [v.o.] Kids, as you know, earlier that year, I'd learned that Lily had broken up not one, not two, but seven of my past relationships.
[cut to Ted and Marshall approaching Lily as she drinks at the bar in MacLaren's:]
Lily: Forget it. I'm retired. I'm out of the game.
Marshall: But nobody's better than you.
Lily: I'm telling you. I swore off that racket. I've gone legit. I'm a matchmaker now.
Ted: Set me up with someone.
Lily: Whoa! I'm just starting out.
