Barney: There's no way she's above the line on the hot-crazy scale.
Ted: She's not even on the hot-crazy scale. She's just hot.
Robin: Wait, hot-crazy scale?
Barney: Let me illustrate. A girl is allowed to be crazy, as long as she is equally hot. Thus, if she's this crazy, she has to be this hot. If she's this crazy, she has to be this hot. You want the girl to be above this line, also known as the Vicky Mendoza diagonal. This girl I dated, she played jump rope with that line. She'd shave her head, then lose ten pounds. She'd stab me with a fork, then get a boob job. I should give her a call.

Robin: Okay, fine, I'll watch it with you.
Barney: Yeah!
Robin: But if either of you makes even one peep about the show being dirty, I'm turning it off. I'm serious.
[on Space Teens:]
Robin Sparkles: Hey Jessica, how's your beaver?
[in the apartment, Ted and Barney spit take]
Jessica Glitter: Great. How's your beaver?
Robin Sparkles: Busy as ever!
[Ted and Barney stifle laughter]
Robin: Our characters had pet beavers.
Ted: [giggles] Sure.
Robin: The beaver is the official animal of Canada. It's our national mascot.
Barney: It's a noble creature.

Robin: Well, I guess you just got to move on. I mean, it's not like you have a shot with Ready McGee over there, right? Ted?
Future Ted: [v.o.] Then I remembered. Cindy had a roommate. A roommate I only caught a glimpse of... But a roommate who, by every indication, was something very special. Was it possible? Could this be the girl attached to that ankle?
Ted: I got to see her ankles.
Robin: You're one of those? God, I swear, one in five guys...

Ted: Yeah, whatever. I'm adding laser tag to the Murtaugh List.
Barney: Jeez, not the Murtaugh List.
Robin: What's the Murtaugh List?
Future Ted: [v.o.] The Murtaugh List is something that came into being around the time I turned 30. It all started with your Uncle Marshall's beer bong. When we were in our early 20s, every time we had a party, that beer bong came out. And around the time we turned 30, same thing. Of course, in our early 20s, the next day would go like this.
[flashback to Ted and Marshall playing around in their underwear]
Future Ted: But by the time we were 30, the next day would go like this.
[Ted on the couch with a sick bucket]
Future Ted: Then one day, in the throes of the worst hangover of my life, I realized there was only one person in the world that I could relate to: Detective Roger Murtaugh, played by Danny Glover in the '80s noir masterpiece Lethal Weapon, known for his oft-quoted catchphrase:
Murtaugh: I'm too old for this...
Future Ted: "Stuff." He said, "I'm too old for this stuff."

Bud: Goodbye, Robin.
Robin: No. You know what? I'm glad you found oot. Because I'm proud to be Canadian. We may not have a fancy NFL team or Prince, but we invented Trivial Pursuit. You're welcome, Earth! Plus in Canada, you can go to an all-nude strip club and order alcohol. That's right. From Moose Jaw to the Bay of Fundy, you can suck down a 20-ounce pilsner while watching some coal miner's daughter strip down to her pelt. Jealous?! In Canada people don't care where you're from, as long as you're friendly and maybe loan them a smoke or hand over a donut. I'm proud to be from the Great White North... and I wish I was there right now. [starts to leave] And we're not afraid of the dark. I mean, we don't love it, but who does?

[flashback to Marshall arriving at the apartment as Ted stacks books on a shelf:]
Marshall: Hey. What's that?
Ted: A 1986 World Book encyclopaedia. [en-sahy-kluh-pay-dee-uh] It's exactly the one I grew up with.
Marshall: Encyclopaedia?
Ted: Oh, you think it should be pronounced encyclo-pee-dia. It's a common mistake. But if you look at that squished together "ae" symbol in this here encyclopaedia, you'll learn that it's a ligature derived from the Anglo-Saxon rune...
[The bookshelves collapse, ripping off a portion of plasterboard and exposing the building's red brick walls]
Marshall: You know, you're gonna have to paedia for that.

Ted: New Jersey is not "pretty much New York". You are not "pretty much New Yorkers".
Colleen: And how would you know?
Ted: Because I live here. That's right. I live here. Yes, we're full of crap. Yes, we pretended to be from out of town so we could sleep with you and leave in the morning. But you know what's even worse than that?! Saying you're a New Yorker when you're not. Because, this is the greatest city in the world and you have to earn the right to call yourself a New Yorker. So why don't you girls crawl into the open sewer pipe you call the Holland Tunnel and flush yourselves back to "pretty much New York"? Because I will do a lot to get laid, but I am not going to New Jersey!

Ted: [on answering machine] Hey, Marshall. Are you lying on the couch right now moping about Lily? You are, aren't you? Well, stop it. She's not worth it. You gotta get over that Grinch.
Future Ted: [v.o.] But I didn't say "Grinch." I said a bad word. A very, very bad word.
Ted: Oh, fudge.
Future Ted: But I didn't say fudge.

Future Ted: [v.o.] Kids, I won't lie, that was a long weekend. More ups and downs than I can count. It was a twisting, turning road that led to the end of the aisle, and not everything along the way was perfect. To be honest, not everything to follow would be perfect either. But what is? Here's the secret, kids: none of us can vow to be perfect. In the end, all we can do is promise to love each other with everything we've got. Because love's the best thing we do. And on that lovely spring evening, that's exactly what Barney and Robin vowed to each other. And it was legendary.

[2020:]
Ted: [v.o.] Aunt Lily wasn't wrong. It was at times a long, difficult road. But I'm glad it was long and difficult, because if I hadn't gone through hell to get there, the lesson might not have been as clear. You see, kids, right from the moment I met your mom, I knew... I have to love this woman as much as I can for as long as I can, and I can never stop loving her, not even for a second. I carried that lesson with me through every stupid fight we ever had, every 5:00 a.m. Christmas morning, every sleepy Sunday afternoon. Through every speed bump, every pang of jealousy or boredom or uncertainty that came our way, I carried that lesson with me. And I carried it with me when she got sick. Even then, in what can only be called the worst of times, all I could do was thank God. Thank every god there is, or ever was, or will be, and the whole universe, and anyone else I can possibly thank... that I saw that beautiful girl on that train platform, and that I had the guts to stand up, walk over to her, tap her on the shoulder, open my mouth, and speak.
